"it is possible to combine two or more plant proteins with different essential amino acids to yield a complete protein."

leonid [27]

Yes i believe it is possible. Complete proteins are proteins with all the indispensable amino acids present in proper proportions; for example in foods like eggs, meat, fish, milk. Incomplete proteins on the other hand are food proteins that contain a limiting amount of one or more indispensable amino acids needed for growth; for example corn tortillas are lacking in lysine. It is possible to make a complete protein by combining together two incomplete protein foods in the same meal.
