It's a good idea to reserve a separate loaf pan just for making savory "cakes" such as this endlessly adaptable one, which includes meat and cheese as well as the usual ingredients: milk, oil, eggs, and flour. You can use any kind of meat in this recipe, including crumbled cooked sausage, shredded chicken, chopped steak, etc. Or you can make a vegetarian version by skipping the meat and using vegetables instead.
