Is there a food that is cheap, delicious and healthy at the same time?
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!
The biggest problem with this is subjective metrics.
"Healthy" depends a lot on both what your needs are and the rest of your diet, there's no one-size-fits-all.
"Delicious" is even more subjective.
'Cheap' at least is fairly objective, but even so different qualities, different locations, or different seasons can change prices drastically, and that's before you get into the fact that what really matters is the more-subjective 'cheap to someone of your means.'
I'd probably argue also that cost should really factor in time / convenience (including prep and washing), perhaps in some places or situations even cost to prepare in terms of energy expense
