First, prepare your beyt meatballs.
Crush the onion, garlic and egg in a blender (If you don't want to use Rondo, you can grate the onion and garlic.)
For meatballs, mix the ingredients, minced meat, breadcrumbs and spices in the blender into a deep bowl and knead the meatball mixture thoroughly.
Take some of the meatball mixture and shape it in a long and flat way in your hand. (Remember, the meatballs will get shorter and thicker while cooking, if you want to extract a large amount, you can make your meatballs thinner.)
Spread greaseproof paper on the baking tray. Put the meatballs you have shaped on the tray
Bake your meatballs for 15 minutes in a preheated 190 degree oven.
When the meatballs to cook, melt the butter
Take one of the doughs and cut it in half. Add butter on a piece in a single layer.
Place the meatballs you take from the oven in a single row without leaving any space on the wide part of the dough, and fold the edges of the dough into a roll.
After wrapping all the ingredients, cut the rolls and place them back in the tray. Put butter on them and put in the oven.
While your kebab is fried in the oven, prepare the tomato sauce. To do this, melt the butter in a pan, add the grated tomato. After boiling for a few minutes, add pepper and salt. (If the consistency is solid , you can add some water.)
After the filo pastries are lightly browned, take them from the oven.
After putting your Beyti kebab on the serving plate, pour the tomato sauce over it, you can put a few spoons of yogurt with it.
