Often there is liquid in the package of Little Smokies; drain off the liquid. Put Smokies in the crockpot. Pour barbecue sauce over Smokies and stir. You want them nicely coated and maybe a little extra.

Put crockpot on low for an hour or two. (I don't remember how long we usually do it, but you don't want your sauce to scorch.) Check periodically to make sure it doesn't burn since the meat is pre-cooked and just needs to be heated through. Leave on warm until ready to eat.
