Arrange chicken breasts evenly in the center of a grill pan. Brush both sides of the chicken breasts with dressing; season with salt and pepper.
Pour remaining 1/4 cup dressing into a mixing bowl. Add tomatoes and basil. Toss to coat evenly with the dressing.
Spread the tomato mixture evenly around chicken in a single layer.
Bake in the Panasonic(R) Countertop Induction Oven using the "Auto Cook" Poultry with Vegetables setting until juices run clear, about 15 minutes. An instant-read thermometer inserted into the center of the chicken should read at least 165 degrees F (74 degrees C).
Remove grill pan and top chicken with the fresh mozzarella cheese. Continue baking until mozzarella cheese is golden brown and bubbly, about 10 minutes.
