The humble chickpea is one of those ingredients that can work in lots of different ways. Mash it, and you’ve got the basis for falafel or a veggie patty. Roast it, and the legume becomes a crunchy snack. Canned chickpeas are convenient and healthy, or you can buy them in their raw state and soak them overnight before using for a fresher, more textural component to a dish. You can even use the liquid left over in canned chickpeas to make a frothy foam similar to egg whites, for use in vegan baked goods and the like.
