Hi Jennifer. We do use a microwave to warm up some of our products. In the case of our Cinnamon Melts, we find it's the perfect way to melt the icing to perfection. However, we never microwave any of our beef, fish, chicken or fries. For example, our beef patties are actually cooked on our grill and our burgers are made to order. We think our food should be enjoyed fresh - after all, that's when it tastes best.
