Step 1

Liberally season both sides of the chicken with salt and pepper.

Step 2

Heat the olive oil over medium-high heat in an oven safe skillet, and add the chicken breasts. Cook the chicken until seared brown, about 3 to 5 minutes on each side. Remove from heat.

Step 3

Spread about 1 tablespoon of pesto over each chicken breast and place skillet in a preheated 400℉ oven for about 15 minutes, until the chicken has reached an internal temperature of 165℉.

Step 4

Remove the skillet from the oven and add two slices of fresh mozzarella on top of each breast, then two slices of tomato each.

Step 5

Place skillet on the center rack of the oven, and turn oven to broil. Watch closely, and remove when cheese is melted and bubbly (about 2 - 3 minutes).

Step 6

If your skillet is not broiler safe, just return the skillet to the 400℉ oven and cook an additional 5 - 7 minutes until cheese is melted.

Step 7

Drizzle the balsamic reduction over the chicken and sprinkle with the fresh basil.
