Is there a food that is cheap, delicious and healthy at the same time?
I have a theory that there is a impossible trinity (like in economics), where a food cannot be delicious, cheap and healthy at the same time. At maximum 2 of the 3 can be achieved.
Is there any food that breaks this theory?
Edit: I was thinking more about dishes (or something you put in your mouth) than the raw substances
Some popular suggestions include
fruits (in season) and vegetables
lentils, beans, rice
mushrooms
chicken
just eat in moderation
Edit 2: Thanks for the various answers. Now there are a lot of (mostly bean-based) recipes for everyone to try out!
Also someone made a community for cheap healthy food after seeing this topic!
Carrots. Same as potatoes. Boil em, mash em, stick em in a stew. Someone already mentioned onions, same idea.
I know your edit says you were thinking about dishes, and I think carrots can be their own dish with very little preparation. I like to bake mine on a sheet for half hour or so at 425f, and they are wonderful on their own. Also so low-calorie you can eat a practically infinite amount of them without spoiling a diet!
Really easy as well! Sprinkle some vegetable oil, salt, pepper and maybe some cumin or paprika on them and bake them until the edges become brownish. Only way to fail is to oversalt them or burning them to a crisp ;)
