Barbecue Meatloaf

1 1/2 pounds ground beef
1 cup fresh bread crumbs (I have never used fresh)
1 onion, diced
1 egg, lightly beaten
1 1/2 teaspoons salt
1/2 teaspoon pepper
2 (8-ounce) cans tomato sauce
3 tablespoons vinegar
3 tablespoons brown sugar
2 tablespoons Dijon mustard (mustard powder is what I normally use)
2 tablespoons Worcestershire sauce
1/2 cup water, to thin sauce if necessary (I have never needed the water)

Preheat oven to 350 degrees F.
Mix together the beef, bread crumbs, onion, egg, salt, pepper, and 1/2 cup of the tomato sauce. Form this mixture into a loaf and place it in a shallow pan.
Stir together the remaining tomato sauce, vinegar, sugar, mustard, Worcestershire and the water (if too thick).
Pour this sauce over the meatloaf.
Bake for 1 hour

Always a big hit easy to make the recipe bigger too.
