Protein-Packed Pesto Summer gardens and roadside stands are bursting with basil in late summer which means it is pesto season. Pesto on pasta is the tradition, but pesto also makes a delectable dressing for beans. For a protein-rich dish with all the best flavors of summer, sauté a chopped onion in extra-virgin olive oil. Drain and rinse one can of red or white beans and stir into the onions. Stir in your favorite pesto sauce. Serve topped with fresh chopped tomatoes and parmesan cheese.
