Preheat oven to 425°F and place a wire rack on a parchment-lined baking sheet.
Combine panko, Parmesan, garlic powder, oregano, and salt in a shallow dish.
Dip each chicken tender in beaten egg and then press into the panko-Parmesan mixture to fully coat.
Place coated tenders on the wire rack and bake for 18 to 20 minutes, flipping once, until golden and cooked through.
Stir together mayonnaise, honey, and Dijon mustard in a small bowl for the dipping sauce.
Serve tenders hot with the honey mustard sauce on the side.
