Tuna Spaghetti Pie

Crust
8 oz. cooked spaghetti
¼ cup grated Parmesan cheese
1 egg, lightly beaten
1 Tbsp. butter, softened
1 tsp. chopped garlic

Filling
1 Tbsp. chopped onion
1 Tbsp. butter, melted
1 Tbsp. all-purpose flour
¼ tsp. garlic powder
¼ cup reduced fat milk
¼ cup light sour cream
1 egg, beaten
6 oz. can tuna, drained and flaked
¼ cup grated Parmesan cheese
1 tomato, thinly sliced

In a large bowl, mix together the first five ingredients. Press onto the bottom and sides of a greased 9-inch pie dish. Set aside. In a skillet, sauté the onion in butter until wilted. Remove from heat. Stir in the flour and garlic powder. In a separate bowl, beat the milk, sour cream, and egg until blended. Stir into the onion mixture. Fold in the tuna. Spoon filling into crust. Sprinkle half the remaining Parmesan cheese over the pie. Arrange tomato slices on top. Sprinkle on the rest of the Parmesan cheese. Bake at 350 degrees for 40 minutes or until crust is golden brown and filling is puffy.
