This is a great meatloaf and especially good on sandwiches. It's a variation of the meatloaf my mother made at my parents' deli. I don't usually measure when I make this, so I'm estimating quantities. My parents made this specially for hot meatloaf sandwiches, served at lunch on Kaiser rolls or rye bread. You can add tomatoes, onion - either raw or caramelized, and/or coleslaw and mayo. I added the sauce to make this a main dish meatloaf if desired.
