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)
- lentils
For year-round availability, bananas seem the most likely fruit. Prices are pushed down because of a short shelf life. High in vitamins and fiber, high sweetness for deliciousness (warning: must like bananas to proceed)
