Ciabatta rolls, split & toasted under the broiler, then rubbed with a cut clove of garlic
Thinly sliced onions
Meatloaf, sliced about ½” thick, and slightly heated {just to remove the chill}
Spread one side of ciabatta with mayonnaise. Top with onions and meatloaf. Top the meatloaf & the other piece of the ciabatta with lots of catsup. Smoosh the sandwich together if it seems too thick.
