A:AnswerYes, you can cook all sorts of things in this. Yesterday I cooked a pork roast and it came out perfect. It has replaced my oven in many things I have cooked.
A:AnswerI don't know why not. I've got it sitting on my counter top and there's no marks on that. Just make sure you leave enough room for either one to vent it they have a vent on top or bottom of your microwave. Great product thou. Very happy with results.
