Meatloaf Sandwich with Sweet Potato Fries

This isn't exactly what you might call a healthy meal but it sure is a delicious one.  Start with some left over homemade meatloaf (worth it's weight in gold, some say).  Slice and sear in a pan then pop it in the oven, melting muenster cheese over top.  Take a loaf of sour dough and toast it in a pan with a little butter until golden.  Then assemble with freshly sliced tomato with S&P and a little Inglehoffer's stone ground mustard.  Serve with piping hot homemade sweet potato fries.  Shazam!
