Tips & Substitutions
For a vegetarian option, substitute the sausage with sautéed mushrooms or spinach. You can use any type of bread, such as whole grain or sourdough, for added flavor. If you're short on time, you can prep the casserole in the morning, but letting it sit overnight allows the flavors to meld beautifully. Consider adding herbs like thyme or oregano for extra depth.
