Can I use Pillsbury premade pie crust for cookie dough?  If so, does it need to be flatten and add a little sugar?  Want to make some fruit filled cookies without making cookie dough.  Thank you. 
 You can put a cup/bowl of water(you can also add some vinegar if you don't mind the smell) in there, heat it up to boiling, let the steam out. Then you should let it sit in the microwave without opening the door.  Wait for a few minutes, open the microwave, and wipe off the inside. All that steam should have soften any stains or food pieces left in there.  You may spray some natural cleaners or lemon/vinegar mixtures to wipe off the inside more.
