Preheat the oven to 200°C/gas 6.
Put 1 chicken breast, skin removed, in a bowl.
Trim and wash a large leek, remove the outer leaves, then slice it into 0.5cm/¼ inch pieces.
Add the sliced leek to the bowl with the leaves of a few sprigs of fresh thyme, a good lug of olive oil, a pinch of sea salt, freshly ground black pepper, and a small swig of white wine and toss together.
Place the leek and flavourings from the bowl into the tray.
Wrap the chicken breast in 4 slices of pancetta.
Drizzle with olive oil, place a couple of whole thyme sprigs on top.
Cook in the middle of the oven for 25 to 35 minutes.
