Good vegetarian bean dishes?

I’ve been trying to add more protein to my vegetarian diet. Making big dishes over the weekend and bringing healthy lunch with me to work. I’ve made lots of lentil soups and black bean soups, and chili. Any other delicious bean dishes or bean salads that I should try? I usually use canned beans (other than for lentils which I make on the stovetop) but I also have a slowcooker if anyone has slowcooker ideas. Thanks!
