Slice the chicken breasts in half horizontally so you have 4 thinner pieces
Pound chicken with a meat tenderizer until it lays flat, but not too thin
Mince garlic
Combine salt, pepper, dried oregano, and dried basil in a small mixing bowl
Season all chicken pieces on both sides with seasoning mixture
Preheat oven to 350F
Heat 2 tbsp oil over medium-high heat in a large oven safe pan - I use a cast iron skillet
Once oil is hot carefully place chicken in the pan
Cook for 2 minutes on each side
Remove chicken from pan and reduce the heat to low
Allow the pan to cool slightly so you don’t burn your garlic
Add minced garlic to the pan and saute for a minute moving constantly so that the garlic doesn't burn
Add the balsamic vinegar to the pan and stir - the balsamic will bubble up so be careful
Add the tomatoes to the pan and increase the heat to medium
Saute for 2-3 minutes
Turn the heat off the stove and add the chicken back to the pan and toss to coat in the balsamic sauce
Top the tomatoes and chicken with mozzarella - I used mini mozzarella balls
Place in the oven to bake at 350F for 10 minutes
Remove from the oven and top with fresh basil and enjoy!
