KNOXVILLE, Tenn. — Here's the Italian Sausage Sub recipe from Metro Pizza in Alcoa. 

Ingredients:

2 links of cooked, sweet Italian sausage, sliced long ways
5 oz marinara sauce
3 oz extra virgin olive oil
8" hoagie roll
Fresh red pepper, green pepper and sweet onion, sliced, (mushrooms optional)
Pinch of crushed red pepper
Sprinkle of Romano cheese
6 oz mozzarella cheese

Directions: 

Saute sliced onions and peppers with olive oil in stove and oven safe pan, on medium heat for about 4-5 minutes. You don't want the veggies mushy, rather a little al dente.

 Add in sliced sausage and continue to sauté for another 4-5 minutes, or until sausage is hot.

 Add marinara sauce and a pinch of crushed red pepper. Add Romano and mozzarella atop veggies, sauce and marinara.

Bake in oven at 450 for approximately 5 minutes.
