In a bowl, combine the breadcrumbs and milk. Allow them to soak for a few minutes.
Add the lamb or beef mince, finely chopped onion, fresh parsley, Turkish sweet red pepper paste, olive oil, ground cinnamon, ground cumin, pul biber, dried mint, sea salt flakes, and coarse black pepper to the bowl with the soaked breadcrumbs. Mix well to combine all the ingredients.
Shape the mixture into 12 patties and set them aside.
Place each potato in a wooden spoon and slice them into slim slices.
In a separate bowl, mix the softened butter with the dried mint, pul biber, chopped fresh parsley leaves, and sea salt flakes.
Spread the seasoned butter mixture over the sliced potatoes.
In a shallow pan or tray, arrange the patties and sliced potatoes in an alternating pattern. Add the sliced onions and cherry tomatoes on top.
Dissolve the chicken or vegetable stock cube in the boiling hot water. Stir in the tomato puree and pour the mixture into the pan with the patties and potatoes.
Cover the pan with a lid or foil and bake in a preheated oven at 180°C (350°F) for 60 minutes.
After an hour, remove the lid or foil and continue baking for another 15 minutes at 200°C (400°F) to allow the top to brown slightly.
Once cooked, remove from the oven and serve.
