Mix together the tomatoes, onion, garlic, vinegar, basil, and half of the olive oil in a bowl and set aside.
Place breadcrumbs on a dish and press the chicken into the breadcrumbs to coat both sides well.
Heat a nonstick pan over medium heat with the remaining oil.
Add the chicken to the pan and cook on both sides till golden brown and an internal temperature of 160 degrees is achieved using a thermometer. Place on a paper towel lined plate to drain excess oil.
