My wife and I do this one from Taste of Home. I sub 50/50 turkey burger and turkey sausage and add shrooms. If you grow zucchini even better.

Zucchini Pizza Casserole
4 cups shredded unpeeled zucchini
1/2 teaspoon salt
2 large eggs
1/2 cup grated Parmesan cheese
2 cups shredded part-skim mozzarella cheese, divided
1 cup shredded cheddar cheese, divided
1 pound ground beef
1/2 cup chopped onion
1 can (15 ounces) Italian tomato sauce
1 medium green or sweet red pepper, chopped
1. Preheat oven to 400°. Place zucchini in colander; sprinkle with salt. Let stand 10 minutes, then squeeze out moisture.
2. Combine zucchini with eggs, Parmesan and half of mozzarella and cheddar cheeses. Press into a greased 13x9-in. or 3-qt. baking dish. Bake 20 minutes.
3. Meanwhile, in a large saucepan, cook beef and onion over medium heat, crumbling beef, until meat is no longer pink; drain. Add tomato sauce; spoon over zucchini mixture. Sprinkle with remaining cheeses; add red pepper. Bake until heated through, about 20 minutes longer.
4. Freeze option: Cool baked casserole; cover and freeze. To use, partially thaw in refrigerator overnight. Remove from refrigerator 30 minutes before baking. Preheat oven to 350°. Unwrap casserole; reheat on a lower oven rack until heated through and a thermometer inserted in center reads 165°. Yield: 8 servings.
