literally like half of my diet is just frying some diced potatoes, onions, meat, and (undiced) frozen peas with some spices.
It’s called “pyttipanna” and is basically the nordic equivalent of fried rice, traditionally made from leftovers and these days i can just buy frozen packets of it (minus the peas) for extremely cheap.
I think of it as human kibble: i’m pretty sure it has every nutrient you need in a pretty decent balance, it’s cheap and trivial to prepare, and it’s so tasty that i can basically eat it every single day (though some variety is still nice, throw in some pickled beets and a fried egg every now and then at least)
peas were given to us by god almighty to just toss into any meal so that no one can have an excuse for not eating some kind of green vegetable.
