Directions
Cook spaghetti according to package directions.
Meanwhile, heat oil in a large saucepan over medium heat. Add onion and bell peppers; cook, stirring occasionally, 5 minutes. Add garlic; cook 1 minute. Add tomatoes and tomato paste; mix well and bring to a boil over high heat. Stir in sausage, olives, and, if desired, pepper flakes. Reduce heat; simmer uncovered 10 to 12 minutes or until sauce thickens slightly.
Drain spaghetti; transfer to four serving plates. Top with sausage mixture, cheese and basil.
