I saw this on my friend, Julie's blog, so I thought I'd put it here. It sounds so so yummy!
Spaghetti Pie (adapted from Cooking Light)
2 cups marinara sauce with seasoned, cooked ground beef mixed in**
4 cups cooked spaghetti, drained
1/4 c onion and chive cream cheese, softened
1 1/2 c low fat sour cream
1/2 c shredded cheddar or mozzarella cheese
Preheat oven to 350F.
Spray a 2qt casserole dish with cooking spray. Mix together cream cheese and sour cream. Put cooked noodles in baking dish. Spread cream cheese mixture over top. Top with marinara meat sauce. Add shredded cheese to top. Bake for 20-30 minutes or until cheese is melted.
**For the sauce, I cooked up 1 lb of ground beef with Italian seasonings and diced onion. I added it to 1 jar of Prego Heart Smart Roasted Red Pepper and Garlic sauce. It was so delicious!
