Baked Mostaccioli

I made this for my son's birthday party (to feed grown ups) and everyone loved it.  It makes enough to serve seven adults and still have leftovers.

Ingredients:

• 1lb uncooked mostaccioli
• 1 1/2 lbs ground beef
• 3/4 cup onion, chopped
• 1 can (14.5 ounces) diced Hunt's tomatoes with spicy red pepper
• 1 can (14.5 ounces) diced Hunt's tomatoes with roasted garlic
• 1 can (8 ounces) tomato sauce
• 1 can (4 ounces) sliced mushrooms
• 1 tablespoon minced garlic
• 1 to 1 1/4 teaspoons salt
• 1 teaspoon sugar
• 1 teaspoon dried basil
• 1/8 teaspoon pepper
• 1 bay leaf
• 2 cups (8 ounces) shredded part-skim mozzarella cheese
• 1/2 cup grated Parmesan cheese

Directions:

1. Cook mostaccioli to package directions; drain and set aside. In a large saucepan, cook beef and onion over medium heat until no longer pink. Add garlic; cook 1 minute longer. Drain.
2. Stir in the tomatoes, tomato sauce and paste, mushrooms, water, salt, sugar, basil, pepper and bay leaf. Bring to a boil. Reduce heat; simmer, uncovered, for 30 minutes, stirring occasionally.
