Directions

• Cook pasta according to package directions until cooked but firm. Meanwhile, in a large nonstick skillet, saute the onion, celery and green pepper in oil until tender.

Transfer to a 2-qt. baking dish coated with cooking spray; set aside.
• In a saucepan, combine the flour, salt, nutmeg and cayenne. Gradually stir in milk until smooth. Bring to a boil over medium heat; cook and stir for 2 minutes or until thickened. Reduce heat; stir in cheddar and mozzarella cheeses until melted.
• Pour over macaroni mixture. Top with Parmesan cheese and tomatoes. Bake, uncovered, at 350° for 25-30 minutes or until bubbly and golden brown. Let stand for 5 minutes before serving.
