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!
Well, something being delicious is subjective, but if we assume a "general acceptance" of most delicious foods, potatoes could fit easily. They can be cooked in all kinds of ways, are very nutritious and, again, pretty much everyone says they're delicious.
That's a good point, but even within potatoes there is perhaps still a trade-off between "delicious" and "healthy". As in steamed potatoes without sauces or stuff is kind of meh, while french fries are not that healthy.
Completely agreed, though I'd also add that to get the most nutrition out of them you want to make sure that you are also eating the skins. (Personally I like the skins anyway, and not having to remove them makes them easier to cook!)
