You'll need 3 shallow dishes big dredge the chicken slices in.
In the first dish, stir together 3/4 cup flour with 1/2 tsp herbes de Provence, 1/2 tsp smoked paprika, 1/2 tsp garlic powder, 1/4 tsp cayenne, 1/2 tsp fine salt, 1/2 tsp black pepper, and 1/4 tsp white pepper.
In a second dish, add the milk.
In a third dish, combine the crushed cornflakes with the remaining 1/4 cup flour and rest of the herbs and spices - 1/2 tsp herbes de Provence, 1/2 tsp smoked paprika, 1/2 tsp garlic powder, 1/4 tsp cayenne, 1/2 tsp black pepper, 1/2 tsp salt, and 1/4 tsp white pepper.
Now that you have your dredging station set up, start heating a thin coat of oil in your non-skillet over medium heat.
Working one slice of chicken at a time, dredge it in the seasoned flour, shaking off any excess.
Then dip into the milk mixture, letting the extra drip back into the dish.
Press into the cornflake mixture, coating both sides and gently pressing so it adheres. Gently lay the breaded slice into the hot skillet.
