Grains eaten with legumes result in a complete protein.
For example, beans and rice are complementary proteins and combining these two foods provides a high quality protein. Complimentary proteins can be eaten over the course of a day. They do not need to be eaten at the same meal. That is because the amino acids are available in the blood for some hours after a meal.
