I made some brisket sandwiches from a brisket I BBQ'd a few months back and froze the leftovers.
The brisket
The bread buttered and sprinkled with Way out west Rub (that stuffs good on everything)
Grilled with Swiss cheese, tomatoes, Brisket and Sauerkraut
Served with Tomato soup, pickles and a homemade Thousand island (mayo, ketchup and grated pickle)
pretty good for leftovers and pantry soup
