The essential amino acids are arginine (required for the young, but not for adults), histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Beans lack methionine but have plenty of the others.
Brown rice has methionine.

Together the have a full complement of the essential amino acids.

Vegetarians also consume cheese, milk, and eggs, which contain the
full complement of essential amino acids.
