Popular throughout the Mediterranean, lupini beans are thin, flat legumes that have been eaten in Northern Africa since at least 22 B.C.E. These Italian beans have a slightly bitter flavor with a silky texture. Often pre-prepared in brine, they are frequently eaten as a cocktail hour snack in Portugal and Spain, and have become popular as a keto-friendly snack. In Italy, lupini beans and olives is a traditional Christmas dish. With a high protein count, lupini are often included in vegetarian dishes.
