1/2 cup melted butter
3 tablespoons chopped onion
2 tablespoons canned whole oregano
2 dashes hot garlic powder
1/2 teaspoon salt
1 cup shredded mozzarella cheese
1/4 teaspoon crushed garlic salt
Spread melted butter in the bottom right-hand corner of a 9-inch pie pan. Place the onion, green onions, spaghetti and mozzarella cheese over the butter in this pan.
Bake in preheated oven for 45 minutes and 15 minutes in the presence of the cheese mixture. Remove pan from oven. Allow to cool slightly. Melt remaining 3 tablespoons butter on top and sprinkle remaining four tablespoons cheese over mozzarella cheese. Cover with remaining spinach. Garnish with remaining mozzarella cheese.
