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!
I tell ya, I tried okra last year and it was a total bust. Had enough seeds to try again this year, started them indoors. Of the 10 seedlings I sprouted, six made it into the ground in March, and only two are still growing. They're by far my slowest growers, but the good news is they look like they're finally picking up speed and are looking strong. They're about 18"-2' tall now. I hope they survive the next 3 months set to have more 100*+ days than not.
