I wanted an easy, laid-back, delicious meal and this looked delicious so I gave it a shot. Also seasoned the chicken before I cooked it up. It was pretty good! Yes, simple, but super easy! Might want to try flavoring the onions a little differently or adding some kind of extra sauce, or not burning the buns...haha. But pretty yummy and the onions smelled spectacular!
French Onion Chicken Sandwich
Recipe from Foxes Love Lemons
1 tablespoon extra virgin olive oil
1 large white onion, thinly sliced
1 teaspoon granulated sugar
2 boneless, skinless chicken breasts, halved crosswise and pounded to 1-inch thickness, if necessary
Nonstick cooking spray
4 slices Swiss cheese
4 hamburger buns
2 cups baby spinach
In large skillet, heat oil over medium heat. Add onion and sugar; cook 25 minutes or until onions are deeply caramelized, stirring frequently. This step can be done up to 3 days in advance. Re-warm onions in microwave or in a small pan on grill before proceeding.
Preheat grill for direct grilling over medium-high heat. Spray chicken with nonstick spray. Transfer chicken to hot grill rack; cover and cook 10 minutes or until chicken loses its pink color throughout and internal temperature reaches 160ยบ, turning once.
Place cheese slices on chicken pieces. Cover and cook 1 to 2 minutes or until cheese is melted and golden brown. Build sandwiches using hamburger buns, spinach, chicken and caramelized onions.
