I thought this might be a fun topic as some of my methods raise eyebrows on occasion. I wanted to reheat two Pasties tonight without firing up the oven. Since I use a dry skillet and lid to reheat sliced of pizza (best way I've found) I employed a similar technique to the Pasties.
Fry pan with lid - I made three balls of tin foil to elevate a diner plate then reheated the Pasties on some parchment - worked like a charm.
When steam started coming out they were done and the crust was still crisp.
