Texas Ranch Chicken

2 teaspoons extra-virgin olive oil
1 1/2 pounds skinless, boneless chicken parts
1 1/2 cups Ranch-style salad dressing
2 cups shredded mozzarella cheese

Heat oven to 350 degrees F (175 degrees C). Spread the olive oil in a 9 x 13-inch baking dish.

Arrange chicken pieces close together in the dish, and cover with the dressing.

Bake for 20 minutes. Remove from heat, top with mozzarella cheese, and return to the oven. Continue cooking for about 15 minutes, until the cheese is melted and lightly browned and the chicken is no longer pink and juices run clear.
