I know! I ran out of foil! I hope they come out ok.
I only tried potatoes in foil, and they were great.
Try red potatoes, butternut squash, beets, red onions, parsnips, carrots: cube all, spray the pot with oil, add veggies and some thyme, and put on high for 3.15 hours. It is my favorite dish that cooks so fast. Esp. the beets.
