Add the egg/egg whites to a bowl and whisk.
In another bowl, add the breadcrumbs, salt, pepper and seasoning of choice.
Mix well.
Dip each strip of chicken breast/mini fillet in the egg whites to coat well.
Remove from the egg mixture and dip into the breadcrumb mix.
Flip over and coat well.
Repeat this process with the rest of the chicken and spray each piece with some 1 kcal spray.
Add the breaded chicken to the air fryer and cook for 20 minutes at 200 degrees Celsius.
Flip half way through cooking and give another few sprays of 1 kcal spray to crisp them up.
If using an oven, spray a lined baking tray well with 1 kcal spray, add the chicken, spray on top again and bake in a preheated oven at 200 degrees Celsius for about 20 minutes until crispy and cooked throughout (flipping after 10 minutes).
**Makes approx. 7 southern fried chicken fillets. If using mini breast fillets, you will probably get 14 mini fillets for the same amount of chicken.
