Recipe Instructions:
4 plum tomatoes (about 12 ounces total), cored and diced
1/4 cup finely diced red onion
2 tablespoons coarsely chopped fresh basil leaves
2 cloves garlic, minced
3 tablespoons olive oil, divided
1 teaspoon balsamic vinegar
1/4 teaspoon kosher salt, plus more for seasoning
2 boneless, skinless chicken breasts, or 4 chicken cutlets (about 1 1/2 pounds total)
Freshly ground black pepper
INSTRUCTIONS
Place the tomatoes, onion, basil, garlic, 1 tablespoon of the oil, vinegar, and 1/4 teaspoon salt in a medium bowl and stir to combine; set aside.
If using chicken breasts, slice each one in half horizontally, starting at the thick end, so that you have 2 (1/4-inch-thick) cutlets (this is known as butterflying). Pat the chicken dry with paper towels and season generously on both sides with salt and pepper.
Heat the remaining 2 tablespoons of oil in a large frying pan over medium-high heat until shimmering. Add the cutlets in a single layer without crowding the pan, working in batches if needed. Sear the chicken until the bottom is browned, 3 to 4 minutes. Flip the cutlets and continue searing until the other side is browned and the chicken is cooked through, 3 to 4 minutes more. Transfer the cooked cutlets to a plate, tent with aluminum foil, and repeat cooking any remaining pieces.
Spoon the tomato bruschetta mixture over the chicken and serve.
