Question

Quizplus · Accepted Answer

Pita bread dipped in mashed chickpeas contains complementary proteins because chickpeas are a good source of incomplete protein, which is complemented by the amino acids found in the pita bread. The other options do not contain complementary proteins. Peanut butter on raw apple slices contains incomplete protein, while whole-wheat crackers with butter and grape jelly and kidney beans mixed with green beans and fresh tomatoes are both sources of complete protein.
