Yield 4 servings

Number Of Ingredients 11

3 pints grape tomatoes, halved
1/4 cup extra-virgin olive oil
1 tsp. white balsamic or white wine vinegar
2 garlic cloves, thinly sliced
1 Tbsp. plus 1 tsp. dried oregano
2 tsp. kosher salt, divided
4 pieces thin-sliced skinless, boneless chicken breast, or 2 skinless, boneless chicken breasts (about 1 lb.)
1 tsp. freshly ground black pepper
10 oz. fresh mozzarella, thinly sliced into rounds
1/2 small red onion, thinly sliced into rounds
1/2 cup peperoncini (about 3 oz.), thinly sliced crosswise

Steps:

Preheat oven to 400°F. Toss tomatoes, oil, vinegar, garlic, 1 Tbsp. oregano, and 1 tsp. salt on an 18x13" rimmed baking sheet.
If using skinless, boneless chicken breasts, slice them into 4 cutlets: Holding knife blade parallel to board, cut breast in half, slicing along a long side, to make 2 pieces.
Season chicken on all sides with pepper and remaining 1 tsp. salt and 1 tsp. oregano. Nestle chicken into tomato mixture. Roast until chicken is almost fully cooked through and tomatoes are starting to burst, 8-10 minutes. Arrange mozzarella rounds over chicken and tomatoes. Return to oven and roast until cheese is melted and chicken is fully cooked through, 2-4 minutes. Top with onion and peperoncini.
