Tips & Substitutions

For a twist, try swapping the eggplant with zucchini or adding bell peppers of different colors for extra flavor. If you prefer a spicier dish, use hot Italian sausage instead. Garlic powder can be adjusted to your taste, or you can use fresh minced garlic for more depth. Additionally, consider adding some crushed red pepper flakes for a kick.

Serving Suggestions

This casserole pairs beautifully with a simple green salad or crusty bread to soak up the flavors. For an Italian twist, serve alongside Melvina'S Low-Fat Spaghetti Sauce or a side of Grilled Italian Sausage And Peppers. A sprinkle of fresh parsley or basil on top before serving adds a nice touch of color and flavor.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in an oven preheated to 350°F (175°C) for about 20-25 minutes until heated through. You can also microwave individual portions, but be sure to cover them to retain moisture.
