Place cereal, salt, pepper, and garlic powder into a food processor and pulse until finely ground and powder-like. Pour mixture into a shallow dish.
Dredge cut asparagus spears in flour and shake off excess (not much flour will stick to the waxy spears, but that’s okay).
Dip each spear into the liquid egg followed by the cereal mixture. Cover each spear in the cereal mixture until fully coated. Season with additional salt and pepper.
Place coated spears onto a parchment lined baking sheet and spray with a light coating of cooking spray. Bake for 15 to 20 minutes or until crisp and lightly browned.
Notes
When making this dish, I used Trader Joe's High Fiber Cereal, which, in my opinion, is a better and healthier version of Fiber One cereal (original). It also doesn't contain aspartame and Fiber One does.
