Open-face Roast Beef on white

What is the face of the sandwich? How do you recognize one from the other on the street? It’s not the outside, but what’s inside that counts. When the top piece of bread is absent, warm roast beef comes out in true glory, bathed in beef gravy and lounging on a single piece of absorbent white bread. You’ll need a fork for this one, friend. Bring its face to yours and taste the flavor.
