In a small bowl, combine the seasoning and place to one side.
Slice the chicken breasts into very thin strips (around 1cm/0.4") and add to a large mixing bowl with half of the seasoning mixed in. To the right of the bowl, place a large shallow dish with the beaten egg, then to the right of that, place a large shallow dish with the Parmesan, Panko and remaining seasoning combined. Finish with a very large baking tray at the end, ready for the fries to rest.
Mix the flour in with the seasoned chicken until full coated, then take a strip, coat it in the egg, then the Panko, then place on the tray. This can be tedious, but think of the crispy goodness in the end. You can do a few at a time, just make sure each strip is thoroughly coated at each stage.
To Fry: Pour enough oil to comfortably fill the base of a large pan and place it over medium-high heat. Once hot (you're aiming for 180C/350F - a breadcrumb should rapidly sizzle), space out a batch of the fries and fry for 1 1/2 - 2 minutes each side until golden and crispy. They should be pretty thin so the meat won't take long to cook. Remove and place on kitchen roll/paper towels and repeat with remaining fries, topping up with oil and bringing back to temperature as needed.
To Air Fry: Space out the fries, liberally spray with oil, then cook at 200C/400F for 8-10 minutes, or until golden and crispy. Again, they should be pretty skinny, so the meat shouldn't take long to cook. You will likely need to work in batches.
Serve up and enjoy with your favourite dip. Check for saltiness and serve with extra sprinkled on top if needed.
