Garbanzo beans or chickpeas are popular in Mediterranean, Indian and Middle Eastern cooking. Pale in color, these irregular-shaped beans have a mild, nutty flavor and a firm texture. Garbanzo beans work well in soups and salads because they retain their shape, even after cooking.
Penne or mostaccioli pasta can be substituted for the rigatoni. Greek kalamata or French niçoise olives can be substitute for the ripe olives.
