Combine the Greek yogurt with half of the paprika (1 tsp) until incorporated. Stir the diced chicken into the bowl and cover with cling film. Pop in the fridge for a minimum of 1 hour, preferably 2-3 hrs.
Next, combine the flour, cornflour, remaining paprika, onion and garlic powder on a plate. Roll the marinated chicken pieces through the mix and place onto a parchment lined baking tray, so that they’re ready to fry.
Add the rapeseed oil to a large/wide frying pan on a high heat. Allow the oil to preheat before placing one tester piece to check if the oil is hot enough. If the chicken sizzles, your pan is hot enough.
Fry the chicken in batches, ensuring they’re well-spaced and not touching. Fry for 2 minutes and then rotate and fry for another 2 minutes.
Remove from the pan and place on a paper towel. Season with fine salt, as soon as they’re off the heat. Keep on a warming plate in a pre heated oven 210°F (100°C) until all of the batches have been fried.
Enjoy with ketchup, BBQ sauce or mayonnaise!
