2. Slice zucchini in your food processor to get very thin slices. Toss zucchini slices with cottage cheese, egg, half of the shredded cheese, and basil cubes. Cover and bake for 30 minutes.
3. Uncover, add sliced mushrooms, and top with remaining cheese.
4. Bake for another 15–20 minutes, or until tops get golden and bubbly.
