PF; We've had a number of great sandwich threads over the years. It might be very cool to have a DC list of the sandwiches that have been previously posted.
I too have been thinking about sandwiches lately. I was going start with a sandwich question. Still think I'll do that, to go along with this thread. Don't want to take away from the op's theme.
Sandwich combination favorites - I'll list just one, because there are too many to list.
Just one of my favorite combinations: The Chief's spice Italian - Whole wheat hogie bun with coarse-grind mustard on the bottom bun, EVOO on top layer. Build from the bottom - sliced onion, sliced black olives, shredded Romaine lettuce, sliced, ripe tomato, slice green pepper, capiacola, Soprasetta, Pepperoni (must be a good, full-flavored, spicy pepperoni), aged provolone cheese.
