Its got to be good. I like the meat to be a 90/10 mix to minimize fat. Must have Carrots, celery, onion, salt, pepper, garlic, parsley, egg, and worcestershire sauce. It can't be too dense, so when you form it to the pan, don't compress it, just let gravity do the work. Add some ketchup to the top and while it baking in a 350 degree oven, make some mashed potatoes served with a brown gravy (preferably from the fat drippings of the loaf). Take a combined loaf and tater bite to enter a state of Nirvana.
