BBQ Shortrib Shepherds Pie

3 Pies in a row? This is an over the top version of shepherds pie I made this past weekend. The idea was to combine the flavors of an end of summer backyard BBQ, pulled pork sandwiches, and shepherds pie. It was a complete success and I suggest anyone to try this update on an old recipe. My only complaint was that I didn’t get to keep the leftovers!
