Is there a food that is cheap, delicious and healthy at the same time? - Lemmy.world

I have a theory that there is a impossible trinity (like in economics [https://en.wikipedia.org/wiki/Impossible_trinity]), 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? [https://lemmy.world/pictrs/image/a523e85e-1280-4932-ae09-8b4b45cd7f4c.jpeg]
