i just rinse whatever bean i’m going with out of the can (i like navy beans and chickpeas) and pour into a bowl then season with a bit of salt, pepper, generous olive oil. then balsamic or if i don’t have that i do lemon juice. if the balsamic is sweet i might do both. simple and good. sometimes i add a dollop of greek or skyr yogurt on top especially if i’m eating black beans.
