Leftover brisket sandwich

I am a big fan of leftovers. I always bring home any food that remains after a meal out and when I've cooked at home, I squirrel away anything that wasn't eaten. I have no qualms about eating steamed broccoli the next day, sprinkled with salt and straight out of the container. However, there are times when I like to put the energy into my leftovers and turn them into something new.

The sandwich you see above was one of my most successful leftover transformations to date. I took a chunk of leftover braised brisket, sliced it into strips and reheated it gently in a small bit of beef stock (not so that it was swimming, just enough to give it some moisture). In another pan, I sauteed some garlic and sliced leeks together until they started to brown and then added a bunch of cleaned and chopped greens (I'm not sure what kind I used, to be honest, they were whatever had come with my CSA share the previous week). I added a bit of water, clapped the lid on and braised the greens until they were tender. I sliced a couple of hoagie rolls lengthwise, toasted them and gently smeared one side with boursin cheese.

Putting the rest of the sandwich together was easy. A layer of greens went down, then the brisket and then I just closed it up. They were amazingly tasty and happily were a full meal, as since the greens were contained within the sandwich, my personal "there must be a green vegetable with every meal" rule was satisfied.
