French Onion Chicken Sandwich

Maybe because it's almost summer, I have been wanting to make lots of sandwiches and salads, like picnic food. I found this sandwich recipe at Foxes Love Lemons. I changed a few things. First, I marinated the chicken in buttermilk for tender chicken. Then I seasoned the chicken with salt and pepper before grilling. I also mixed up ranch dressing and balsamic vinegar and spread that on the toasted buns and I also added tomatoes. Great recipe even if it was chilly and rainy when I grilled.

French Onion Chicken Sandwich

1 T. extra virgin olive oil

1 large white onion, thinly sliced

1 t. 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 c. 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 160°, 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.
