Budget food

[Mirage]

Pasta is always super cheap. You can even make a big pan of meatless sauce (which is cheaper) & keep it in the freezer for future meals.

This is what I do. Lots of veggies and trout. I do use a tiny bit of meat though, but it isn't a lot compared to everything else.

Instant noodles. I don't know if they're still 9p, probably more like 19p now, but still - alright with a side of similarly priced beans when you're poor.

Might as well just eat white flour. Don't forget that an important part of eating is to avoid malnourishment.
