Start by creating your production line. In one bowl mix together, egg and half of the lemon juice with the garlic puree and set aside.
In the blender add ½ of the gluten free oats until it resembles fine oats.
Place the blended oats in one bowl and then the non-blended oats in the other. Mix them up so that you take 25% of the blended oats into the non-blended and vice versa. This then means that you have 2 bowls one with majority blended and the other with majority unblended. The blended is now your fake flour and the unblended is your fake breadcrumbs.
Season the fake flour bowl with salt, pepper, mustard and parsley.
Season the fake breadcrumbs with salt, pepper and basil.
Slice up the chicken breast into medium sized tender shapes.
Place the chicken tenders into the flour bowl, then drench it in the egg mixture, then heavily coat it in the breadcrumbs mixture.
Then gently place it in the Air Fryer basket. Cook for 10 minutes at 175c/350f.
While they are cooking make your mayonnaise. Mix some regular mayonnaise with the last of the lemon, salt, pepper and a little mustard powder and mix well.
10. Serve.
