How about sardine & mustard sandwiches? For me, the best part of a sandwich is the bread/roll. I'm not partial to white bread. I grew up in a Polish neighborhood in Chicago and I remember, as a kid, going to the local bakery at 5:30 AM to pick up fresh (and still piping hot) loaves of rye bread. The crunchy crust was the best part. Bread should never be packaged in plastic - it should be bought fresh and eaten the same day. My first wife drove me nuts when she would buy several loaves of bread at the supermart and then put them in the freezer.
