Pre-heat the oven to 400°F and grease a 16x20 baking sheet.
Crush the Pringles, using a gallon bag and rolling pin or a food processor.
Then add the crushed chips or potato crisps to a gallon bag with the seasoned salt, seal the bag, and shake it around to mix.
Cut the chicken breast into small 1-2 inch nuggets.
Dip the nuggets in the buttermilk.
Then place the nuggets, 2-3 at a time, into the gallon bag, and shake them around to coat them with the Pringles chip breading.
Place the nuggets in a single layer on a baking sheet.
Then bake the Pringles crusted chicken at 400°F for about 20 minutes, or 'til they're cooked thru. At this point, you can remove them from the oven and let stand, uncovered, about 5-10 minutes to crisp up even more.
Serve with your favorite chicken dipping sauce, with fries, or salad on the side.
