I only buy salmon a few of times a year, too and then I add potatoes.
Oh dear, where do you keep your refrigerated products then? It's cold in winter, but what do you do in summer?

We do three years now without a fridge and it works fine. We eat what gets spoiled easily and most things you do not need to keep in a fridge at all. Eggs for example, same with fruit and vegetables. My fridge was always empty. If the children get an icecream or I buy yogurt we eat it at once. It works fine this way plus my house is cold for the biggest part of the year.
Happy day 💕
