How I Pack a Lunchbox That Gets Me Through 8 Hours at the Bank Counter

Monday morning, 6:15 a.m., an insulated lunch bag is spread open on the kitchen counter. Two containers from the fridge, one small ice pack, a fork, a napkin. I've been repeating this routine for close to ten years now, but it wasn't this tidy from the start. I'll never forget the smell when I opened my desk drawer around 2 p.m. after leaving a tuna sandwich in there in the middle of summer. The colleague next to me, Petra, wrinkled her nose and said, "Sabine, did something die?" From that day on, I started seriously researching packed lunches.

The first thing to understand is that a bank teller's work environment is pretty unfavourable for packed lunches. There is a staff fridge, but our branch is on the second floor and the fridge is in the basement break room. Lunch breaks are short, so by the time you go down and come back up, you have roughly ten minutes to actually eat. That's why most days I keep my lunch in a drawer, or on the shelf behind the counter. In winter, when the heating works well, the room temperature climbs to around 23 degrees, and in summer it feels quite warm even with the air conditioning. Under these conditions, food has to hold up from 7 a.m. until 3 or even 4 p.m.

The Basics of Containers and Keeping Things Cool

The first thing I changed was my containers. I used to use disposable zip bags or flimsy plastic tubs, but if the seal isn't tight, salad dressing causes a disaster inside your bag. Now I use two glass containers with airtight lids. Glass is heavy, but it doesn't absorb odours, and if you put it in the fridge the night before, it retains the cold a bit longer. Slip a small ice pack into the insulated bag and everything stays cool enough until lunchtime. I rotate about three ice packs from the freezer, each one cost around 2 euros, if I remember correctly.

The key rule is to never put hot food and cold food in the same bag. If you put soup in a thermos and place a salad container next to it, the heat from the thermos turns the salad lukewarm. When I want something warm in winter, the thermos goes separately in an outer pocket of the bag.

The Weekly Pattern

I gave up early on the idea of cooking every morning. I usually invest about an hour and a half on Sunday afternoon to prepare Monday through Wednesday. Thursday and Friday's meals I make on Wednesday evening. There's a reason I split it this way: after more than three days, no matter how well you refrigerate things, vegetables get soggy and the flavour drops off sharply.

Here are a few combinations I make often:

• Couscous mixed with roasted squash, feta cheese, and sunflower seeds. The dressing is just olive oil and lemon juice. This keeps well for up to two days.
• Two slices of wholemeal bread with smoked salmon, cream cheese, and capers. To keep the bread from getting soggy, I spread cream cheese on both slices. It acts as a moisture barrier.
• A variation on Kartoffelsalat. Boil and cool the potatoes, then toss them with pickles, onion, and a light mustard dressing. I tend to avoid mayonnaise-based versions in summer because they make me uneasy.
• Lentil soup in a thermos. This is strictly for winter. Heat it up in the morning and it stays quite warm until lunch.

As for cost, my weekly lunch ingredients run roughly 15 to 20 euros. A single Brötchen and a coffee at the nearby bakery costs close to 3 euros, so if you buy lunch out every day on top of that, you easily spend 8 to 10 euros a day. Over a month, the difference is substantial. With Hamburg's cost of living being what it is, this is less about saving money and more of a survival strategy.

Lessons Learned from Failures

I'll be honest about the combinations that don't work.

I've given up on anything with avocado. No matter how neatly you slice it in the morning, by lunchtime it's browned and turned a dull, murky green. Even sprinkling lemon juice on it barely helps. Pasta salad is another one. The noodles soak up all the dressing, so by the time you eat it's a dry, clumpy mass. Packing the pasta separately and mixing right before eating does work, but then you need three containers and your bag gets heavy. At that point, I'd rather just pick a different meal.

Rice actually works surprisingly well. Cook it the night before, refrigerate it, and bring it cold in the morning. Top it with a little soy sauce, sesame oil, and sautéed vegetables, and it's delicious even cold. There are quite a few Asian grocery shops in Hamburg, so sourcing the ingredients is no problem.

One more thing about wrapping. Wrapping a sandwich in aluminium foil does keep the bread from drying out, but when acidic ingredients (tomatoes, pickles) touch the foil, you sometimes get a metallic taste. Switching to beeswax wraps solved that problem. Beeswax wraps cost a bit more upfront, but they last a long time, so in the end they're better than foil.

Little Rules for the Desk Drawer

I have my own rules for storing lunch in a drawer. Never stack paperwork on top of the bag. Once I set a client file on top of my bag, and condensation from the ice pack seeped into the documents. Fortunately it wasn't anything important, but since then I always make a dedicated spot for the lunch bag at the very back of the drawer.

When I eat at my desk during lunch, I open the container lid slowly. If you pop it open fast, the contents can splatter, and getting dressing stains on your blouse behind the counter means spending the entire afternoon self-conscious about it. It's a small thing, but these little annoyances add up and make you want to quit packing lunch altogether. The moment you think, "Forget it, I'll just grab something from the bakery," it usually stems from exactly this kind of hassle.

Rinse the containers with water right after eating. There's a sink in the break room so it's not difficult, but if you put it off, you end up scrubbing dried-on food at home and getting annoyed. That annoyance eventually turns into "I'm not packing lunch tomorrow." The secret to maintaining the routine isn't elaborate recipes, it's how simple you make the cleanup.

On Fridays I usually ease up. I'll throw together whatever ingredients are left over from the week, or just go out and eat somewhere nearby with my colleagues. The moment you become obsessive about packing a perfect lunch every single day, you won't last long. Four days a week is plenty.

These days, grabbing the lunch bag in the morning is as automatic as brushing my teeth. Sometimes it's fun to try a new recipe. Last week I brought a North German style Matjeshering salad, and a colleague remarked, "That smell is intense." Unlike Petra's tuna incident, this time I just laughed and closed the lid. I've decided herring is strictly for Fridays from now on.
