I never heard (or thought) of putting potatoes on a sandwich, but ok. Hold the pickles and I'm there. This looks fabulous (as always) -- and since it's a second meal made from left-overs, it's basically free. I doubt that I could keep The Weasel from snacking it into oblivion long before lunch the next day -- but it's worth a try. Nice job. (Love the sesame seed bread.)
