If I have something that is frozen and is in a foil dish or wrapped in tin foil I just bung it in the microwave for a minute or two, likewise if I've heated something in the oven in a foil dish and it's just not quite hot enough I finish it in the microwave.
Husband and mother say I shouldn't do this. I've done it for years with no effect on microwave or quality of food.
I guess what I am asking is, do other people do this.kkk
