Drizzle the olive oil in the baking tray.
Make the breadcrumbs by placing the bread into a food processor and blitzing until you reach a fine breadcrumb texture. Pour the breadcrumbs into the baking tray on top of the oil and add the garlic powder, oregano, sweet smoked paprika and salt and pepper, combining it all together with a spoon.
Bake in the oven for about 6-7 mins until they are starting to crisp and become golden. Remove from the oven and leave to one side.
Next, place the Greek yoghurt into a bowl and whip until smooth using a spoon – this will loosen it to make it easier for coating the chicken.
Using clean hands, cut the chicken into equal nugget sized chunks – roughly 2″ diameter.
Use tongs to dip each piece of chicken into the yoghurt and then into the breadcrumbs – pressing down to coat the chicken evenly. Place each coated nugget on to a baking tray. Continue until you have coated all of the chicken pieces.
Place the tray of chicken nuggets in the oven at 180 degrees and bake for 10-12 minutes or until they are piping hot and cooked through.
