Preheat oven to 425°F and line a baking sheet with foil or parchment. Spray lightly.
Put flour and half the salt-pepper in one bowl. Whisk eggs and milk in a second bowl. Mix crushed cornflakes with spices in a third bowl.
Dredge each tender in flour, dip in egg, then press into cornflakes. Lay on sheet and drizzle or brush with melted butter.
Bake 12–15 minutes until edges brown and internal temp is 165°F. Flip once halfway for even crisp.
Serve with ketchup or ranch. Shortcut: use store-bought frozen tenders and re-crush cornflakes for fresh crunch.
