Wash the chicken under cool running water. Pat dry with paper towels. Next, evenly distribute the salt and pepper over both sides of the chicken. Set aside.
In a large, oven-safe skillet, over medium heat, add the olive oil and allow the pan to get hot - about a minute or so.
Lay each chicken piece, skin side down, in the hot skillet. Brown on each side for about 2 minutes. (You may need to do this in batches. Do not over crowd the pan.)
Remove the chicken from the skillet and transfer to a plate.
Pour the stewed tomatoes into the pan and stir in the basil and oregano.
Add the chicken back to the pan, skin side up. Place in oven and bake for 25 minutes.
Remove from oven. Top chicken with mozzarella slices. Return to oven for 5 minutes.
