I'm making this tomorrow...

1 1/2lbs of lean hamburger
2 eggs beaten
1/4 cup bread crumbs
1/4 cup mayo
1/4tsp salt
1/4tsp pepper
2tbs worsteshire sauce
8oz cheddar cheese
12-15 pieces cooked bacon (crumbled up)
Mix all these ingredients together
Then combine in a small bowl 1 cup ketchup and 1/2 cup yellow mustard
add half of the ketchup mixture to meat and mix well.
after dumping in pan, pour the rest of the ketchup mixture on the meatloaf
bake for 40 min at 425 degrees
top with french fried onions and bake for another 10 min

This turns out much better in a regular baking pan than a loaf pan.
