Spaghetti Pie

Ingredients
1 pound ground round
1/4 teaspoon salt
1/4 teaspoon black pepper
2 (8-ounce) cans tomato sauce with garlic
1 1/2 cups low-fat sour cream
1/2 cup chopped green onions
1/4 cup (2 ounces) 1/3-less-fat cream cheese, softened
4 cups hot cooked spaghetti (about 8 ounces uncooked pasta)
Cooking spray
1 1/3 cups (about 5 ounces) shredded reduced-fat extra-sharp cheddar cheese
Preparation
Preheat oven to 350°.

Cook meat in a large nonstick skillet over medium heat until browned, stirring to crumble. Drain well, and return meat to pan. Stir in salt, pepper, and tomato sauce. Bring to a boil; reduce heat, and simmer for 20 minutes. Combine the sour cream, green onions, and cream cheese in a small bowl, and set aside. Place the spaghetti noodles in a 2-quart casserole dish coated with cooking spray. Spread the sour cream mixture over spaghetti noodles. Top with meat mixture. Sprinkle with cheddar cheese. Cover and bake at 350° for 25 minutes. Uncover; bake an additional 5 minutes or until cheese is bubbly.
