• 4 tbsp. oil
• Juice of 1 lemon, divided
• kosher salt
• Freshly ground black pepper
• 1 tsp. Italian seasoning
• 4 boneless skinless chicken breasts, pounded to even thickness
• 3 roma tomatoes, diced

1. In a small bowl, combine oil, juice of ½ lemon (about 2 tablespoons), 1 tsp salt, 1/4 tsp pepper, and Italian seasoning and whisk to combine. Transfer to a large re-sealable bag along with chicken. Seal and chill, 30 minutes.
2. Transfer chicken to a preheated grill and discard excess marinade. Grill chicken over medium-high heat until cooked through, 5 to 7 minutes on each side.
3. Meanwhile, combine diced tomatoes and remaining juice from ½ lemon. Season with salt and pepper, to taste. While chicken is still on grill, top each breast with 1 slice Provolone and cover grill until cheese is melted, 2 to 3 minutes. Top chicken with tomato mixture and serve.
