I am not exactly sure what you have there, but I reheat mine in a corning dish with a cover and put it in the OVEN at 350 25 to 30 min. with just a dab of water in the dish. I NEVER microwave mine because it drys things out and does not stay hot for very long.
Thanks Spunky, it is a whole turkey (small ) and sides.
One year, we didn’t have an oven. I put the 20+ lb bird into the just large enough microwave. Just a bit ago, family was saying that was the best turkey ever, so moist and tender. They say that every year for the past nearly 40 years. And it was a goooood bird.
