Which cooking mode should I use in a microwave for heating up cooked food?
To warm up food in a microwave after it has been cooked would be to use the microwave mode and not the grilling mode. There are a few microwaves that are made now that allow you to grill or cook food in the oven. Even though there are specially made pans that you can now use in a microwave oven to cook food in, I don't think the food taste the same. I tried to cook a chicken breast one time in a microwave because the oven on our stove was not working. The truth, it was not the same at all and seemed to taste a bit funny to me.
