I've revived an old recipe that my mother always made. The leftovers, should you have any, make for excellent sandwiches.
1 1/2 lbs hamburger (I find that 80% lean is a good choice)
2 - 3 slices bread, torn into pieces
1 tsp salt
1/2 tsp pepper
splash Worcestershire sauce
about 1/4 cup milk
about 1/4 cup ketchup
chpd green pepper, maybe 1/2 to 1 whole - if desired
American cheese, cut into small bits, as much as you want - if desired
If desired, additional ketchup and a few slices bacon for the top
Combine the meatloaf ingredients. Spray a 9 x 13" pan with PAM and put 3 slices bread, side by side, to place the meatloaf on top. This will absorb the grease, and when you're done with them, is a tasty treat for your dog; if he can handle it. Pat the mixture into a large loaf, on top of the bread. Spread some ketchup on top of the loaf, and lay a few slices bacon on top, if you'd like.
Bake 350 degrees for about 1 hour, 15 minutes, or until no longer pink.
