Meatloaf Sauce

I always have to call Mom when making Meatloaf to confirm how to make the sauce for the top of the Meatloaf. But, one night I decided not to call and instead to look it up on the Internet. It used the same ingredients as Mom's recipe so I went for it. It was great! Now only if I had a great recipe for Meatloaf. Anybody??

Mix:
1/4 C ketchup
1/2 t mustard
2 t brown sugar
