Zucchini Cheese Casserole

Directions

1. Place zucchini in a double thickness of cheesecloth; sprinkle with salt. Let stand for 10 minutes. Gather ends of cheesecloth and squeeze out as much liquid as possible.
2. In a bowl, combine zucchini, 1/2 cup mozzarella cheese, Parmesan cheese and eggs. Press into a greased 13x9-in. baking dish. Bake, uncovered, at 400° for 20 minutes or until crust is set.
3. Meanwhile, in a large skillet, cook beef and onion over medium heat until no longer pink; drain. Stir in the tomato sauce, garlic powder, and oregano; bring to a boil. Spoon over crust.
4. Top with green pepper and mushrooms; sprinkle with remaining cheeses. Bake 25-35 minutes longer or until heated through and cheeses are melted.
