For the BBQ sausage just cover beef cocktail sausages with your favorite BBQ sauce and bake (or slow cooker) until hot.

My favorite:
Brown Sugar Links

1 lb. sliced bacon
1 pkg. small beef cocktail sausages
1-2 cups brown sugar

Open bacon and cut the long stripes into thirds. (I do this before removing the bacon from the plastic liner.) Roll each sausage in one piece of bacon.

Place in pan or casserole dish with sides.(Sauce may boil over if you do not do this) When all sausages are rolled and in pan,pack brown sugar over all. You may have to use more brown sugar. Make sure you have a thick coating over all. This is the secret. Bake at 350 degrees for 1 hour or until the bacon is crisp. Everyone loves this recipe. Hope you do also.
