Sprinkle both sides of chicken breasts with salt, pepper and Italian seasoning. Set aside.

In a large saute pan over medium-high heat, warm 1 tablespoon of the olive oil. Add chicken, cover pan, and cook for about 10 minutes. Flip chicken breasts and continue cooking until the chicken is cooked through.

While chicken is cooking, in a medium saute pan over medium-high heat, warm remaining 1 tablespoon olive oil. Add garlic and cook for about 1 minute, or until fragrant. Add halved tomatoes and continue to cook until tomatoes skin starts to wrinkle, about 5 minutes. Remove from heat and stir in basil. Set aside.

Once the chicken has reached desired doneness, place a piece of mozzarella on top of each chicken breast. Pour tomato mixture on top. Cover pan with lid once more and let the mozzarella melt, about 1-2 minutes.

Finish it off with a drizzle of balsamic vinegar and enjoy.
