Spaghetti Pie

2 tsp olive oil
1/4 cup shredded Parmesan
1 egg
1/2 lb ground beef or turkey
1/2 cup chopped onion
1 jar spaghetti sauce or homemade sauce
8 oz cottage cheese
1/2 cup mozzarella cheese

Stir olive oil into drained spaghetti. Stir in Parmesan and egg. Form spaghetti into a "crust" in a greased baking dish (I use a 9 x 11). Spread cottage cheese onto crust. In skillet cook beef and onion until meat is brown. Drain. Stir in sauce. Heat through. Put meat and sauce mixture in center of crust. Baked uncovered at 350 degrees for 20 minutes. Remove from oven and sprinkle mozzarella on top. Bake until melted. (about 5 minutes)
