BEAN NEET strongly recommends it.
Rather than being the most expensive staple food, think of them as the cheapest nutrients.
You will get all rather than none of the fibre, 2/3 of your protein rather than none, and a ton of nutrients, some of those nutrients (iron) are valuable.

Do the math, 500g dried kidney beans, big tin of tuna, dozen eggs. You couldn't even buy mince with that money these days
