I told you — Turks like stuffing everything, and here is just one example. If you wish, you can make this dish vegetarian by using more rice. I won’t take any offence. Perhaps you think zucchini are boring old vegetables, but they are delicious this way.
When cooking the rice for the lamb stuffing, ensure it is still firm to the bite, as it will continue cooking in the stuffing. If you have any leftover stuffing, roll it into small balls and fry them until just cooked through.
