Cook pasta according to package instructions. Drain and keep warm.

Meanwhile, in a large skillet over medium high heat, brown sausage for 4 to 6 minutes, stirring until small crumbles form. Drain fat if needed. Add onion and pepper, and cook for 4 to 5 minutes, or until tender, stirring occasionally. Stir in Pasta Sauce and bring to a boil. Cover, reduce heat to medium low and simmer for about 10 minutes, stirring occasionally. Sprinkle Parmesan cheese on top and serve hot with cooked pasta.
