Creating authentic Turkish Tantuni is simple when you follow these steps:

1. Marinate the Meat: In a bowl, combine the thinly sliced meat with olive oil, salt, pepper, red pepper flakes, and cumin. Let it marinate for at least 15 minutes.

2. Prepare the Vegetables: While the meat is marinating, chop the onion, garlic, tomatoes, and green bell pepper. Set aside.

3. Cook the Meat: Heat a large skillet over medium-high heat. Add the marinated meat and cook until browned and cooked through, about 8-10 minutes.

4. Add Vegetables: Add the chopped onion, garlic, tomatoes, and green bell pepper to the skillet. Stir well and cook for an additional 5 minutes until the vegetables are tender.

5. Assemble the Wraps: Lay a piece of lavash or flatbread on a clean surface. Spoon a generous amount of the meat and vegetable mixture onto the center of the bread.

6. Garnish: Sprinkle chopped fresh parsley over the filling. Squeeze some lemon juice for added flavor.

7. Wrap It Up: Fold the sides of the lavash over the filling and then roll it tightly from the bottom to the top to create a wrap.

8. Serve: Repeat the process for the remaining lavash. Serve the wraps warm with optional pickles or hot sauce on the side.
