1/2 cup butter, softened
1/2 cup finely chopped onion
3 cloves garlic, minced
1 (2 ounce) can tomato paste
1 (16 ounce) package low-fat cream cheese, softened
1 (12 ounce) package frozen chopped spinach, thawed
1 (8 ounce) package cream cheese, softened
2 tablespoons grated Parmesan cheese
Preheat oven to 350 degrees F (175 degrees C).
In a medium saucepan, cook butter, onion, garlic and tomato paste over medium heat for about 15 minutes, stirring occasionally.
Remove from heat and stir in cream cheese and cheese. Mix well and pour mixture over pasta.
Bake uncovered in preheated oven for 20 minutes. While pasta is baking, layer cream cheese and remaining cheese over the top of the pasta.
Turn pasta out and sprinkle with Parmesan cheese. Bake for about 5 minutes, or until cheese is melted and the cheese is bubbly.
