Hi folks! Black beans are a very good source of protein for vegetarian. Blood-builder. Yesterday, I made a pot of black bean soup(black bean, groundnuts, red dates, tong sum, wolfberries). After scooping up the soup to thermos, I used the remaining ingredient to fried basmati rice(added mint leaves from garden and carrots)...talking about no wastage/one bean makes two dishes :) cheers!
