Place 2 large square sheets of baking paper on a baking tray.
Put the chicken breast fillets onto each paper, then take one of them and fold the paper up slightly and pour half the dressing over the top.
Hold the pieces of paper together and fold over twice at the top, then fold the ends in twice to make a sealed parcel.
Repeat for the second chicken breast parcel.
Bake in the oven for 20 minutes.
Remove from the oven and open up the parcels to allow the chicken to cool. Serve hot, warm, or cold with your favorite side dish or salad. Or cut into slices and keep in a container in the fridge for later use as a sandwich chicken or for snacks.
