Bean Burger Patties

In a medium bowl, mash pinto beans with a fork. Add cheese, bread crumbs, chopped red onion, cumin, garlic salt, pepper and parsley. Add egg white and stir until well combined. Shape bean mixture into 4 (1/2-inch-thick) patties.

Heat oil in a large nonstick skillet over medium-high heat. Add patties to pan; cook 3 minutes on each side or until patties are browned and thoroughly heated.

In a small bowl, combine mayonnaise, ketchup and mustard. Place patties on bun topped with lettuce leaves, mayonnaise sauce and red onion slices. Serve with carrot sticks, if desired.
