Italian Sub Sandwiches

Directions

1. In a large cast-iron or other heavy skillet, cook sausage over medium heat just until no longer pink; drain. Add the onions, peppers and garlic. Cover and cook for until vegetables are tender, about 25 minutes, stirring occasionally. Add tomatoes and oregano. Cover and simmer until tomatoes are cooked, 5-6 minutes. Season with salt and pepper.
2. Meanwhile, hollow out bottom of each roll, leaving a 1/2-in. shell. (Discard removed bread or save for another use.) Toast rolls. Fill with sausage mixture.
