Ingredient substitutions: You can easily swap the sausage for turkey sausage or even diced ham for a different flavor profile. Soy or plant-based sausage works well for a vegetarian option. Optional variations: Feel free to load it up with your favorite veggies like bell peppers, spinach, or mushrooms for added nutrition and flavor. You can also try different cheeses such as Monterey Jack or feta! Storage or reheating tips: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for about 15 minutes or in the microwave, covered, for 1-2 minutes until warmed through.
