I should confess to having eaten a couple of home-assembled pastrami sandwiches tonight. I'd been craving this for a while. Instead of my purist pastrami-mustard-rye version, I wanted my home-brewed Rueben-ish cole slaw version. It only takes a minute to make a great one, and most of that time is spent separating the thin layers of pastrami to stack it properly.
The local ingredients:
Boar's Head (ubiquitous deli brand in the northeast) pastrami, sliced very thin.
Finlandia (imported, aged) swiss cheese (a favorite), also sliced very thin.
Shop Rite store-baked seeded rye bread.
Shop Rite store brand cole slaw (I have yet to find my ideal in cole slaw, but this fills the bill).
Stack at least a quarter pound of the pastrami on a plate. Put a slice or two of swiss cheese on top. Nuke for 15 seconds. Remove, flip it, add a slice of swiss to the other side, nuke for another 15 seconds. Place this steaming pile of heaven on one slice of the rye bread. Add the cole slaw, the other slice of bread, and press the sandwich closed. (I like a pressed sandwich.)
Eat.
Repeat.
