2 pounds of boneless, skinless chicken breasts, sliced crosswise to 1 inch thickness
1 Tablespoon Extra Virgin Olive Oil
1 Large white onion, thinly sliced
1 Tablespoon granulated sugar
4 Slices Swiss Cheese
Nonstick Cooking Spray
4 Hamburger Buns
2 Cups of Baby Spinach
1. In a large skillet over medium high heat, add the oil, onions and granulated sugar and cook for 25 minutes until deeply caramelized, stirring constantly. This can be done up to 3 days in advance. Re warm onions in the microwave or in a small pan on the grill.
2. Preheat grill for direct grilling over medium high heat. Spray chicken with non stick cooking spray, and place on a hot grill rack, cover and cook 10 minutes or until no longer pink, turning once.
3. Place cheese slices on chicken pieces. Cover and cook around 1-2 minutes until cheese is melted and golden brown.
4. Build your sandwich by starting with chicken, then the spinach, then the onions. Enjoy!!!
