/ck/ - Food & Cooking

i dont own a fridge. i live in a western first world nation. don't ask me how that happened and thats just how it is. it has been that way for years.
anyway .. i want to challenge myself to spend as little as possible on food and groceries this month.

heres the challenge:
>food needs to be able to survive without a fridge
>should have some variety
>as cheap as possible
>i cant buy food every day so ideally i want to go to the store maybe once a week so the food should last for 7 days

i been eating a lot of pasta cause thats the only thing i can come up with here but even pasta needs some stuff that also needs a fridge like parmesan cheese or so. im just not very creative to come up with new solutions or ideas. i usually spend around 150€ or so a month on food (average). the last 3 months i been keeping it at around 100€ but i know i can do better.
i know the obvious solution is to buy like 15kg of pasta for 20-30 bux and to eat that for 30 days but there has to be something else that i can do.
