Put the chicken in a bowl with the olive oil, garlic, lemon juice and zest and thyme, and season with salt and freshly ground pepper. Leave to marinate for at least 20 minutes – ideally a couple of hours or overnight.
Rinse the potatoes thoroughly in cold water, then pat them dry in a tea towel.I leave the skins on, but do as you prefer.
Toss the potatoes with the olive oil, thyme, salt and freshly ground pepper, and roast until crisp in a preheated conventional oven (top and bottom heat) at 220°C for about 25-30 minutes, or in an air fryer at 205°C for about 25-30 minutes – or until golden and crisp.
Meanwhile, fry the chicken in a pan until golden and cooked through – use the marinade it has been sitting in. Set the chicken aside on a chopping board and let it rest.
While the chicken is cooking, blend the ingredients for the whipped feta in a mini chopper or similar. Season to taste with freshly ground pepper – salt is usually not needed.
Toss the crisp potatoes with the parsley and crumbled feta.
Spread the whipped feta over 4 plates. Place a piece of chicken on top and scatter the crisp potatoes over it.
Drizzle with a little olive oil and sprinkle with parsley and freshly ground pepper.Serve with freshly baked bread, if you like.
