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]

IMHO, steamed vegetables are right in the middle of the triangle. I've bought a steam cooker and it's a game changer compared to boiling. It's healthier since less nutrients are lost, preserves so much more taste and texture, there's a timer so you can start the steamer and go do something else. Also makes you use less water. I've still got to try steamed fish but I expect it'll taste great.
on a perhaps relevant note air-fried stuff may also fit the category. like air fried sweet potato chips, delicious even without seasonings!
