I do mine just a little differently--it's more like a roast . I just
offer it as a suggestion, but my family and neighbors wouldn't have it
any other way. No tomatoes.

1 lb.ground beef
1/2 lb. pork sausage meat
Chopped onion
2 eggs
1 1/2 to two cups of bread crumbs
A good bit of Poultry Seasoning (sage, thyme, rosemary, parsley)
salt and pepper
(if you can't find ground pork in the meat section you can use Jimmy
Dean sausage .)

Put this in a large bowl, and mix it thoroughly with your hands.
Use a large, rectangular metal pan, (I use one that has a teflon type
coating inside.)

Make the meatloaf into a "loaf" shape and place it in the pan. (Do
"not" cook it in a loaf pan)
Bake 350 degrees, til done and a bit of crust starts to form in the
pan.

Remove loaf to a serving platter. Make a good brown gravy with the
drippings, and season it well. (I add a very small amount of garlic
powder at this point, you don't really detect it in the taste, but it
definitely adds something. )
Slice, not too thick, and serve with gravy.

It also makes wonderful sandwiches, with mayonnaise and lettuce.
