"You really don't have to reheat them because they can be eaten at room temperature. However, if you want to serve it warm, put it in a 350 degree oven, covered with tin foil for about 35-45 minutes. If you are in a hurry, slice off some pieces, fan them out on a cookie sheet, cover with foil in a 350 degree oven for 15-20 minutes. YUMO!"
There you go!
Edit: When all else fails go to the HB website. It is a perfectly cooked product when you get it.
