Moist, tender and delicious, our USDA Certified Chicken Breast come from chickens humanely raised without antibiotics. Each Chicken Breast is about a pound. The chicken breast comes from the large pectoral muscle on the underside of the bird. The breast is the largest source of white meat and is both lean and tender. Its large size makes it versatile in the kitchen and its nutritional value makes it a popular choice. Tenderloins, a particularly tender section, are technically part of the breast but often sold separately.
