Brown sausage in skillet.
Break lasagna noodles in half and cook as directed. Drain.
When noodles are cooked add them to the skillet of browned sausage. Add in spaghetti sauce, ricotta cheese, 1 cup shredded mozzarella cheese, mushrooms and diced green pepper.
Cook until melted and well heated, about 10 minutes on medium heat. Stir so ricotta is distributed evenly.
Put remaining 1 cup mozzarella cheese on top, sprinkle fresh basil on top. Cover and cook until cheese is completely melted.
