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 :)
Pumpkin is one of my favorite things to add to chili. It serves as a thickener and makes the flavor richer, more bodied.
Chopped Sweet potato is a vegetarian chili addition. I’m personally mixed on it, but it compliments the beans well.
