Preheat the oven to 190°C/gas 5.
Lightly oil a baking sheet and crack an egg into a bowl and beat it.
Put the flour onto a large flat dish and the breadcrumbs in another dish.
Cut the chicken into bite-sized pieces and place onto the plate of flour then mix so they each piece is coated, separating the pieces so they’re not touching each other.
Suggest you wash your hands now as you will get very sticky otherwise.
Pick up a piece of chicken, shake off any excess flour, dip into the egg and place on the breadcrumbs.
Sprinkle more crumbs on top to fully cover the chicken and place on the baking sheet.
Repeat until all the nuggets are coated.
Bake for 12-15 minutes until the outside is crispy and lightly browned.
