4 cups shredded zucchini, moisture squeezed out
1 cup shredded mozzarella
1 cup shredded cheddar
2 eggs, slightly beaten
1/4 t salt
1/4 t garlic salt (I add 1 heaping teaspoon of minced garlic as well)
1 pound ground beef
1 medium onion, chopped
8 oz can tomato sauce
2 t oregano (I usually use Italian seasoning)
1 green pepper, cut into thin strips
1/4 pound mushrooms, sliced
1/3 cup Parmesan
Mix zucchini, 1/2 of cheeses, and 2 eggs. Press into 10x15 greased cookie sheet. Bake at 400 for 30 minutes.
Brown burger with salts, until very fine crumbles. Add onions and cook until crisp. Stir in tomato sauce and oregano. Spoon over hot crust. Arrange green peppers and mushrooms on top. Sprinkle with remaining cheeses. Bake an additional 10 minutes or until cheese is bubbly and golden. If desired top with sliced tomatoes.
