Ground Beef: For 1 pound ground beef, substitute 1 pound ground turkey, ground chicken breast, cooked lentils, or black beans. All of these options have less fat and a similar amount of protein. If you choose lentils or black beans for your burgers or meatballs, mash them slightly so they hold shape better.
Hamburger Patty: For each patty, substitute a Portobello mushroom.
Beef Rib-Eye: For 1 pound beef rib-eye, substitute 1 pound beef sirloin, which has half the calories and fat, and more protein.
Chicken Thighs: For 1 pound chicken thighs, substitute 1 pound chicken breast, which has less calories and fat, and an equal amount of protein.
