Preheat the oven to 400 F.

In a large bowl, whisk together the lemon juice, vinegar, and 1 tablespoon olive oil, then add the chicken, salt, and pepper and toss to coat.

Add the remaining tablespoon olive oil to a skillet over medium high heat. Once hot, add the chicken and sear for 3-4 minutes, until browned, then flip the chicken and sear for an additional 2-3 minutes, until browned, then turn off the heat.

Add the tomatoes to the pan, then top the chicken with the mozzarella cheese, and bake for 15 minutes, until the cheese is browned and bubbly and the chicken is fully cooked.

Garnish with fresh basil and serve!
