Quite disparate levels of technology you've got there! When defending yourself against an attacker, are your options flint spear or laser pistol?

Because if so, you might enjoy Fallout 2 😉

Sandwiches? I did sandwiches and snacks.

Tfw you're an Dutchy and simple home-prepaired sandwitches (read two slices of bread with some butter and cheese between them, nothing fancy), are the countries national breackfast and lunch. Warm food is for dinner traditionally 🤣.

Either way, sandwitches (no need to limit to peanut butter, a lot can be put on bread!), salads (pasta or normal), fruit, veggie, cheese, and certain type of meat (like smoked or dried sausage, or beef). They all make great parts for cold meals you can keep in your bag till lunch (speaking from experience). Some cheese & meat are even packed per small packages for easy take along as snack usage.

I would suggest you do go to restaurants a few times, just to try the local cuisine (or their variation of other cuisines). But it probably will be expensive for you indeed. Whenever I'm in Asia, I feel rich (and I'm really not). Even Japan, who is often said to be expensive, is cheaper than my country. Especially when it comes to food.

Hey, you're correct it's pretty expensive to buy food here.

If you want to try and get a feel for some of the prices you can try your luck here with Google translate -> https://kronan.is/snjallverslun (this store is much nicer and just as cheap as the self proclaimed discount supermarket Bónus)

Expensive stuff includes but is not limited to; fresh meat and fish, most non basic fruit, fresh pastries, non factory bread, meat toppings, cheese, good yoghurt, most cereal, and more. Basically anything good and healthy. It's gotten much worse in the past two years compared to the other Nordics because the icelandic aristocracy has taken a real liking to greedflation. All the fast food and restaurants are crazy expensive. Anywhere a tourist might go is also crazy expensive.

The less expensive foods might include: basic fruit like banana and some type of apples, factory made bread, cheaper types of biscuits, cheaper types of pasta and canned goods, cheaper types of yogurt. Some dried fruit and nuts. You should be ok with making sandwiches as someone else suggested.

Good luck, try not to get stuck here for too long 😅

I was just in Iceland for a week or so. Restaurants were a bit on the expensive side coming from the US, but not terrible. Cheap sandwiches abound there, though: at most gas stations or the supermarkets I could get a premade sandwich for $4 US or so. I largely did day tours as well, and all the ones I went on stopped at a couple of gas stations through the day for pit stops and food, and the sandwich selection was adequate. Personally,I wouldn't stress too much.

Couscous. It can be "cooked" in cold water if necessary. It also goes well with most things so if you find something you can afford, perhaps you can add it.

Ask the locals though, what is affordable there.

Not sure about Iceland, but several countries place some constraints on which foodstuffs you can enter the country with (not asking about importing, etc, even for personal consumption). I’d check this beforehand.

Sushi

Pasta salad is one of my go-to lunches on the go. Fusili pasta mixed with any and all vegetables you prefer. For protein I'll add boiled eggs, beans and/or fried chicken strips. Easy to make, nutritious and good to eat cold/room temperature.

Iceland is amazing, hope you have a greta trip!

Beans, lentils and rice are highly nutritious, can all be eaten cold or at room temperature and won't spoil if you make them the day before and keep them in a closed Tupperware.

Go to the supermarket and get ready-made meals. It's way cheaper than restaurants and you'll get to try local delicacies :)

A caponata sandwich with a shed load of cheese should keep you going for a while. Or if you don't want to make caponata, grill some veg instead.

Not sure if it’s in your list, but the hot dog places were immensely popular and quite cheap when we were there a few years ago. Bæjarins Beztu was very tasty. Ate hot dogs with crispy onions and remoulade A LOT when we got home to recreate them. Even if you can’t take them with you during the day tours I’d recommend trying it out anyway.

Order some Huel before you go. Just add water and you are good.
