Use a sharp knife to butterfly each chicken breast in two.
Place the chicken breast pieces into a plastic zipper bag (or folded in parchment paper if you prefer) and use a meat pounder or rolling pin to pound them out until thin and even.
Sprinkle 0.5 teaspoon of the salt all over the chicken pieces and set aside.
Whisk up the egg in a bowl large enough to fit a chicken breast piece.
Combine the oats, flour and remaining salt and seasoning in a large flat bowl.
Dredge each chicken piece in the egg and then the oat mixture. Set aside on a plate.
Heat up oil in a non-stick skillet to about 150 C / 300 F.
Fry the chicken immediately for about 3-4 minutes per side until golden brown.
