Pigeon peas are small, round legumes that belong to the species Cajanus cajan. They are commonly grown in tropical and subtropical regions and are known for their resilience to drought. Pigeon peas can be harvested when young and green or left to mature and dry for later use. These peas are a staple food in many cultures, particularly in India, Africa, and the Caribbean. They are rich in protein, fiber, and essential nutrients, making them a valuable addition to various dishes, including soups, stews, and curries.
