Sorry about the last picture being crooked, but that is what the potato looks like when it's done before all the good toppings. I didn't put any water in with the potatoes when I was cooking it and they turned out fine (to my surprise). Although, I would rather cook my potatoes in the oven, this did the trick too. It will work on those days when there just isn't enough time to get everything done.
