Adjust the oven rack to the center position. Preheat the broiler to HI. Set a wire rack on top of a rimmed baking sheet. Spray with nonstick oil; set aside.
In a medium bowl, whisk together the eggs and flour. Add the Worcestershire sauce, hot sauce, garlic powder, Cajun seasoning, and black pepper. Stir until fully incorporated.
Place the Panko bread crumbs in a shallow bowl. Dip a pickle slice first into the egg mixture, then coat with the Panko bread crumbs. Set on the greased wire rack. Repeat with remaining pickle slices.
Broil for about 3 minutes on each side. Serve immediately with Ranch dressing.
Freezing Instructions: Before broiling, place coated pickle slices in a single layer on a parchment-lined baking sheet. Flash freeze for 20 minutes. Transfer frozen pickle slices to a labeled freezer bag. When ready to prepare, preheat the broiler to HI and broil on the greased wire rack set in a baking sheet for 4-5 minutes on each side.
