A pork sausage! Pretty tasty. The best way to make these are to mix up a bunch of your favorite barbeque sauce enough so that when you put a bratwurst in it it would be covered in sauce. Now on a grill slowly grill your brats. At some point you want to put the BBQ sauce in a metal pan and put that on a warm part of the grill (off to the side) so that the sauce warms up. After the bratwurst have finished grilling put them in the barbeque sauce and let them sit in there and soak up some sauce for a while. Now stick in a hot-dog bun and enjoy!
