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, beans
- rice
- mushrooms
Look into Indian foods and even traditional japanese. Really hearty and nutrient dense foods there. Plus there’s a book on Depression era cooking that has a lot of great recipes for low cost and self sustaining.
