To avoid a watery casserole, make sure to drain excess moisture from vegetables like spinach and tomatoes before adding them. You can customize this dish by adding bell peppers, zucchini, mushrooms, or olives. For a dairy-free version, omit the feta or use a plant-based alternative. This casserole is ideal for meal prep and can be stored in the refrigerator for up to 4 days or frozen for longer storage.
