Novice question about defrosting/reheating homemade meat pie

[WhenDoISleep]

A few weeks ago I made a (very tasty) beef and onion pie in shortcrust pastry. As the pie was so big, I froze about 1/3 for use at another time.

I really am not sure though how I go about defrosting/reheating without

a) making the pastry soggy
b) burning the pie (as it was obviously fully cooked prior to freezing
c) underheating it for consumption so risking making DH and I ill

Any advice would be gratefully received.

Um, try separating the pastry from the meat, heat the meat up good and proper til piping hot in the microwave and eat the pastry cold?
