Preheat oven to 300 degrees F.
Fill a large pan with the chips. (I use a large disposable foil roasting pan)
Spray chips with non-stick cooking spray. Sprinkle HALF the Parmesan cheese and Ranch Dressing Mix over chips. Toss to coat.
Bake in oven for 10 minutes. Carefully and gently stir in remaining cheese and Ranch seasoning over chips. Toss again.
Bake chips another 10 minutes. Remove from oven and sprinkle with fresh chopped Parsley. Serve immediately and enjoy!
