I just had to make one and decided on bacon wrapped smokie links, in the crock pot. For a 5 QT slow cooker I used
2 lbs bacon cut into 3 equal pieces (open package and cut while it is still together makes it easy)
3 packages smokie links or small cocktail wieners.
wrap a piece of bacon around a link, secure with toothpick and put into cooker
when you have a layer sprinkle brown sugar on top and small amount of BBQ sauce
keep adding layers. Run slow cooker 4 hours on low.
