How would you cook twice baked potatoes and stuffed mushrooms on the grill?

[Laura]

I have twice baked potatoes and stuffed mushrooms....the kind you get at the meat counter....and I want to make them on the grill with the steaks.

Should I wrap them in foil, or just set them in the foil and leave open.....and what do you think, top shelf....10-15?

Thanks!
