Preheat oven to 425ºF. Grease a baking sheet lightly with olive oil or cooking spray.
Crush the cereal slightly by giving it a quick crumble in your hands. There's no need to crush it into a powder. Empty the cereal onto a large dish.
Mix in all the herbs and spices in a small bowl. Add 3 tablespoons of the herbs and spices to the cereal and stir everything together. Save the rest of the spice blend for another dish. Be sure to store it in a sealed container.
Place several pieces of chicken at a time onto the cereal mixture, and bread all sides of the chicken pieces. Place the breaded pieces on the baking sheet in a single layer.
Bake the chicken for about 12 to 15 minutes.
Let the popcorn chicken cool for a few minutes and serve immediately for maximum crisp.
