Preheat the oven to 400 degrees F. Drizzle 1 tablespoon of olive oil onto a rimmed baking sheet and evenly spread it out to coat the bottom of the pan. Sprinkle with Italian seasoning, 1 tablespoon of salt, and a few grinds of black pepper. Scatter the cherry tomatoes on the baking sheet, ensuring they are evenly coated with oil and seasoning. Arrange the chicken in the center of the sheet while pushing the tomatoes to the edges, and drizzle the remaining tablespoon of olive oil over the chicken.

Bake in the oven until the tomatoes are soft, blistered, and beginning to burst, about 20 to 25 minutes.

While the chicken is baking, add the balsamic vinegar to a small saucepan. Bring it to a boil over medium-high heat, then reduce the heat to medium. Simmer until reduced by half and thick enough to coat the back of a spoon, approximately 7 to 8 minutes.

Remove the baking sheet from the oven and place a slice of mozzarella over each chicken breast. Return to the oven and bake until the cheese melts, and an instant-read thermometer inserted into the thickest part of the chicken reaches 160 degrees F, about 5 to 7 minutes. The chicken will carryover cook to 165 degrees F.

Sprinkle the chicken and tomatoes with torn basil leaves and drizzle with the balsamic reduction. Spoon the pan juices over the tomatoes and chicken. Serve on a bed of baby arugula with crusty bread for soaking up the pan juices.
