Notes
Substitute pork sausage with turkey or chicken for a lighter version.
Add vegetables such as bell peppers, mushrooms, or spinach for extra flavor.
Use different breads like sourdough or French bread for varied texture.
Make it vegetarian by skipping the sausage and increasing the vegetables.
Store leftovers for up to 4 days and reheat in the oven or air fryer for best results.
