Wagon wheel pasta pizza casserole

I love quick and easy casseroles for those busy nights at our house.I found this one at tasty kitchen and will be making it sometime this week.

4 cups Wagon Wheel Pasta, Uncooked
1 pound Bulk Italian Sausage
½ cups Green Pepper, Chopped
1 cup Mushrooms, Sliced And Sauteed
28 ounces, weight Pasta Sauce
½ cups Pepperoni, Chopped
¼ cups Ripe Black Olives, Sliced
2 cups Mozzarella Cheese, Shredded

Heat oven to 350 degrees F.
Cook and drain pasta according to package directions and set aside.
While pasta is cooking, cook sausage in skillet over medium heat, stirring occasionally, until no longer pink. Add the green peppers to the skillet and saute for about 5 minutes. Add the rest of the ingredients to the skillet, except for the cheese, and mix well.
Pour pasta mixture into an ungreased 2 1/2 quart casserole dish. Cover the dish and bake about 30 minutes or until hot and bubbly.
Sprinkle with cheese and bake uncovered about 5 minutes or until cheese is melted.
