Mashed chickpea salad sandwich is a healthy vegetarian sandwich that is a little similar to a tuna sandwich and has lots of protein from the chickpeas (garbanzo beans), making it a perfect lunchtime option for vegetarians and vegans, or anyone who likes tuna salad, chicken salad or egg salad sandwiches and looking for an alternative. If you need a vegetarian mock-tuna salad recipe, this is the recipe to try. Made with flavors and ingredients similar to a chicken salad or a tuna salad, this chickpea salad is made with chickpeas, mayonnaise, mustard, celery, and sweet pickle relish. You could add in a little fresh dill if you happen to have some on hand as well, and, depending on personal preference, you might want to add in some diced onion or even some chopped green onion. Chickpeas make a great meat substitute in this sandwichIf you just make chickpea salad (and not sandwiches with bread), all the ingredients are gluten-free, though you might want to check the mayonnaise, mustard, and relish of any additives. Need it to be vegan? Just use an egg-free vegan mayonnaise (my favorite brand is vegenaise) in place of regular mayonnaise, since all of the other ingredients are egg-free, dairy-free and vegan.
