Cut the beef into very small pieces.

Marinate the beef with yogurt, vinegar, lemon juice, salt, black pepper, and mixed spices. Let it marinate in the refrigerator for at least 1 hour.

Grill or roast the beef in the oven, turning occasionally. Shortly before it's fully cooked, add the diced bell peppers, onion, and tomatoes, along with a little pomegranate molasses.

Cook for about 1 hour or slightly less, until fully done. Serve with tahini sauce, onions, sumac, and French fries, wrapped in tortillas.
