Everything you love about a chicken caesar salad plus it's on a handy-dandy bun!
4 boneless skinless chicken breast halves (4 oz each)
1/4 tsp each salt and pepper
4 slices red onion
2 tbsp butter, softened
4 hamburger buns, split
2 cups torn romaine lettuce
1 tbsp grated Parmesan cheese
1/2 cup creamy Caesar salad dressing, divided
Sprinkle chicken with salt and pepper. In a large skillet coated with cooking spray, cook chicken over medium heat until juices run clear, turning chicken at least once. Remove and keep warm. Cook the onion slices in the same skillet until tender.
Spread butter over cut sides of buns. Place buttered side up on an ungreased baking sheet. Broil 3-4 inches from the heat for 1 minute or until golden brown.
Toss romaine lettuce with Parmesan cheese and 1/4 cup dressing; spoon onto bun bottoms. Top with onions, chicken and remaining dressing. Replace bun tops and serve!
