Put 2 chicken breasts, skin side up in a small baking dish and season.
Squeeze the lemon into a bowl and stir in the honey and soy sauce. Spoon the mixture over the chicken, then tuck the squeezed-out half of lemon between the pieces (this will moisten and add flavour to the chicken).
Roast the chicken breasts in a baking dish, uncovered, for 30-35 minutes in a preheated oven (190C/gas 5/fan oven 170C). Cook until done and richly glazed, basting with the juices at least twice. To check if they are done, prod the chicken with your finger - if it's still a bit soft, give it a bit longer.
Serve with salad and potatoes roasted with herbs and garlic.
