For a vegetarian option, substitute the pork sausage with plant-based sausage or simply omit it and add other vegetables like bell peppers or zucchini. Adjust the amount of cayenne pepper according to your preference for heat. A pinch adds a gentle warmth, while a larger amount provides a more pronounced spiciness. Feel free to experiment with different types of apples. Honeycrisp, Granny Smith, or Gala apples all work well in this recipe. This dish can be prepared ahead of time. Simply assemble it and store it in the refrigerator until ready to bake. Add an extra 10-15 minutes to the baking time if baking from cold.
