A riff on the British Sunday roast, this Eastern Mediterranean roast lamb is served with autumnal veggies and spätzle dressed in the fresh flavours of spinach, feta and parsley. It's a nod to the food culture that Turkish immigrants brought with them to Germany. But, don't let the highfalutin concept get in the way: it's a delicious meal and, importantly a slow-cooked treat that won't stress out whoever is cooking the Sunday roast.
