Barbeque Chicken

4 boneless, skinless chicken breasts
Homemade BBQ Sauce
2 cups tomato sauce
1/3 cup brown sugar
1 teaspoon liquid smoke, optional
2 tablespoons spicy mustard
Salt and pepper to taste

Place all ingredients in a baking dish. Bake at 350 degrees for approximately 30 minutes; turn chicken occasionally. Cook until sauce has thickened and chicken is cooked through. You really want the sauce to get thick and sticky! Yummy. Serves 4.
