I ordered a big BBQ beef brisket joint in my online shop, which was out of stock, and has been replaced with a pack of plain '3 thin cut brisket slices' 
What the Jeff can I do with them? Scared to cook them like I would a big piece of brisket because they look quite lean and they'd probably end up the size of nuggets. They're about 6 inches long and maybe an inch (if that) thick each.
I can see me just shoving them to the back of the freezer, help!
