This recipe was originally adapted from the good ol' Better Homes and Gardens plaid cookbook. I changed it around a little because I don't really like using fillers like cracker crumbs or breadcrumbs. I tend to think of the crumbs as being evil, little, thirsty sponges absorbing all of the fats and grease that would, otherwise, drain out. I confess that I have used TVP (texturized vegetable protein) as an extender when I just didn't have enough ground meat. Grated carrots, mushrooms, zucchini and/or other vegetables can be added in the uncooked mix to lighten up the density. By the way, the leftovers make an unbeatable sandwich! My husband likes to doctor his meatloaf sandwiches up with mayonnaise, ketchup and hot sauce.
