Combine the cup of whole milk and lemon juice in a bowl and stir. Leave at room temperature for 5-6 minutes until it thickens slightly. Take the chicken breast and cover in a layer of cling film on a chopping board and using a rolling pin smash it out so it's the same thickness all the way along so it cooks evenly.
Place the chicken into the milk and lemon mixture. Refrigerate for around ten minutes.
In a bowl combine the oats, flour and dried spices and garlic and season well with salt and pepper. Stir to combine well. Tip out onto a tray or dinner plate. Dredge the chicken in the flour mixture until well coated.
Heat up a large frying pan with around 1/2 cm oil in until hot enough that if you put a tiny bit of flour in it sizzles. Preheat your oven to 180 degrees. Fry the chicken for a few seconds each side in the hot oil until golden. Then transfer it into a wire rack and bake until cooked through, this should take around 20 minutes.
Remove from the oven, and baste the crispy fried chicken in peri peri sauce until glazed. Serve up in a burger or with your choice of sides and enjoy! :)
