Luscious Lean Burgers

INGREDIENTS:

• Olive oil cooking spray
• 1 lb extra-lean ground beef (96%)
• Sea salt, ground black pepper or other burger seasonings, to taste
• 4 1-oz slices reduced-fat Mozzarella cheese
• 4 whole-wheat hamburger buns(100 calorie)
• 1 tsp olive oil
• 1/2 sweet onion, sliced

INSTRUCTIONS:

1. Ensure you have 2 racks in oven and preheat oven to 350°F. Line a rimmed baking sheet with foil and mist with cooking spray.
2. Place beef into a medium bowl.  Divide mixture into quarters and form each portion into a patty.
3. Place burgers on baking sheet and cook to desired doneness on bottom rack, flipping once, about 12 to 15 minutes for medium-well. About 2 minutes before removing burgers from oven, top each with 1 slice cheese and place buns on top rack to toast, being careful not to let them burn.
4. Meanwhile, heat oil in a small skillet on medium-high. Add onion and sauté until translucent. Remove and set aside.
5. Remove burgers from oven, place on buns and top with onion. If desired, garnish burgers with your favorite veggies such as chopped tomatoes and sprouts (shown here).
