What to do with leftover pork is generally up to the person who finds it lying, forlorn, in a tupperware container in a refrigerator. A resourceful person, however, might learn the ways of refrigerator wisdom, remove the pork from the refrigerator and chaperone it with BBQ sauce. They might then cut up the pork into small pieces and put it into a saucepan with a few squirts of BBQ sauce to keep the poor things company.
Unobtrusively lighting the burner underneath the saucepan is vital to the operation. Soon, the small pieces of pork are warm and getting along well with the BBQ sauce and it is no time at all before the resourceful person whom I mentioned in the beginning of this entry has scooped them into the empty space between two pieces of bread and began to munch happily on their barbecue sandwich.
