Guajes (Leucaena leucocephala - aka haujes, cuaje, hauxaya, guaje beans, wild tamarind) are a vegetable used in Mexican and some SE Asian cuisines - the long, flat, stiff green/brown pods of the Leucaena tree. Inside the pods are small red or green seeds (roughly the size of pumpkin seeds) with a grassy, garlicky & slightly bitter flavor.
Guajes seeds can be extracted from the pods as you would peas. Once extracted they are eaten raw, roasted, pureed, or dried (whole or ground) as a high protein snack, vegetable side or as an ingredient in other dishes.
