Directions

Press and flatten biscuits onto the bottom and up the sides of a greased 11×7-in. baking dish; set aside.
In a skillet over medium heat, cook beef and onion until meat is no longer pink; drain.
In a bowl, beat eggs. Add spinach and mushrooms; mix well. Stir in the cheeses, garlic powder, salt, pepper and beef mixture; mix well. Spoon into prepared crust. Drizzle with butter.
Bake, uncovered, at 375° for 25-30 minutes or until crust is lightly browned.
