First, wash the chicken, remove the extra skins, and then chop into 3 to 4 cm quarters.
After chopping the chicken, pour it into a large bowl. Now peel and wash the onion, then chop it into slices and pour it into the bowl containing the chicken.
At this stage, add sour lemon juice with salt, black pepper, yogurt, and saffron to the bowl. Now combine the ingredients in the bowl for 1 to 2 min.
After mixing the ingredients, add the olive oil to the bowl, and mix it with the material for a minute.
Cover the bowl with cellophane and refrigerate for 2 hours in the refrigerator to flavor chicken meat. If you have enough time, you'd better mix chicken meat out of the night before with the ingredients and refrigerate.
After the chicken was flavored, remove it from the refrigerator. Now place the chicken pieces on a flat surface.
Hold the pieces of chicken by hand, then pass the skewer through them. When the chicken is skewered, skewer the tomatoes. At this stage, prepare the brazier and place the skewers on the brazier at a distance of 4 cm from the heat.
Now, you have to turn the skewers every 1 minute to grill the chicken evenly. Once the joojeh kabab is ready, place the tomatoes on the grill to cook.
Now, if you wish, you can also rub a little melted butter on the kebabs. In the end, serve the kebabs to your taste with fresh bread or Iranian rice.
