This is a family favorite, and our PKU'er will eat it as his main course.
The phe depends on how much ranch powder you add, and how many potatoes you use.
8-10 red potatoes
3 TBS. dry ranch dressing powder
1/8 c. vegetable oil
Preheat oven to 425. Cut potatoes into quarters (no need to peel). Toss in oil until coated. Add dry ranch dressing powder, toss to coat. Bake for 40-50 minutes until soft and browned on top.
