I was thrilled when I saw I was not the only one who made this Meat Loaf. It has been around a long time now. But I notice the 1/4 cup of vinegar was missing. You add the vinegar with the tomato sauce, brown sugar,and mustard. That combination is what makes this recipe so good. When I make stuffed green peppers, I make this recipe with rice in place of the cracker crumbs, then stuff my peppers and Microwave them, like I do with the meat loaf. Whether I am making meat loaf or stuffed green peppers, there is never any left overs.
