Preheat oven to 425 degrees. Spray a large baking sheet with non-stick spray. Place cut chicken into a bowl. Add ranch dressing and toss to coat. In another bowl mix chips, onions and cheese. Individually roll chicken pieces in chip mixture, then placing them on baking sheet. Don't crowd. Use a second pan if needed. Bake 20 minutes.
Notes: I found a recipe for chicken crusted with cheese crackers and couldn't wait to give it a try. It turned out that I was out of cheese crackers so I did my usual - I decided to Think With My Taste Buds and came up with this recipe. Changes can be in the cheese. Pepper Jack would be wonderful and give it a touch of heat or you can increase the onions and add more flavor.
