Flavor does not matter, presentation does not matter but the food shouldn’t make you sick, and should ideally have enough calories per day for the average person to survive (2000 kcal min).
Edit: I am not in any danger of starving or malnutrition, nor am I insolvent. I’m mainly asking this question out of curiosity on how people would approach a solution :)


This is also false. All plants have all essential amino acids. You are citing debunked and dated research.
I found a reasonably recent (2019) source that splits the difference here, acknowledging that all the amino acids are present in each plant BUT the quantities of some amino acids in any given plant are not high enough to meet human dietary needs.

I’d be happy to not cite ‘debunked and dated’ research, except I can’t cite debunking and updated research for the lack of it in my life.
