This pie can be served cold or hot. If you'd like to reheat it, place a single slice in the microwave and heat in 30 second increments until warmed through. Alternatively, you can place it in the oven at 350F for about 15 minutes until warm. Add 5-10 minute increments if you need to heat it further. You may want to cover it loosely with aluminum foil to protect the crust from over-browning if reheating in the oven.
