I have lots of versions of chickpea salads. One of my faves for quickness, flavor and economical is a form of Greek salad. Chopped cucumbers, red onion, tomatoes, feta cheese, lemon juice, olive oil and pepper and of course washed chickpeas. Very tasty especially on day two.
Another good salad is a variation of tabbouleh, parsley, mint, pepper, garlic, lemon juice, tomatoes, shallots, and instead of bulgar use chickpeas.
I basically add chickpeas to any salad that has flavor, as I find them kinda boring otherwise. Which is weird because I love hummus, but I generally eat that with veggies or other flavor packed food.
Also spiced and baked chickpeas make an awesome healthy treat. I use a no sodium Mexican spiced mix.
