Put the olive oil into a wok or a large frying pan on a medium heat. When smoking, add the chicken to the pan and season a little. Cook, tossing, until every part of the chicken gets really caramelized and golden brown (this should take around 12–15 minutes) and the skin is very crisp.
Halfway through this time – so, after about 6 minutes – add the smashed garlic. When the garlic starts to get a little golden, add the chillies and bay leaves. Cook for a minute, keeping everything moving in the pan, then add the lemon zest and juice, with the parsley.
Take off the heat, season to taste, and serve.
