Cut the pointed cabbage into quarters and place them in an ovenproof dish. Drizzle with olive oil and season with salt and freshly ground pepper. Roast in a preheated oven at 220°C (conventional oven) for 40 minutes.*After 20 minutes, turn the oven down to 200°C – the cabbage continues roasting alongside the chicken.
Heat a splash of oil in a frying pan. Season the chicken with salt and freshly ground pepper and brown it quickly on both sides.
Place the chicken in an ovenproof dish and put it in the oven with the cabbage. Lower the heat to 200°C and bake for about 20 minutes more, or until the chicken is cooked through. The time depends on the size of the breast fillets.
Fry the courgette slices briefly in the same pan used for the chicken, season with salt and freshly ground pepper and set them aside, loosely covered with foil.
Cook the shallots and garlic in the same pan until the shallots are soft and translucent, then add the orzo and stock. Simmer until the orzo is almost tender. Adjust the consistency with more stock if needed.
Stir in the ricotta along with the lemon zest, juice and herbs - and season to taste with salt and freshly ground pepper.
Slice the chicken and serve with the lemon orzo, roasted pointed cabbage and fried courgette.
