Wash the chicken and marinate it with spices, tomato sauce, garlic, 2 tablespoons vinegar, and salt. Mix well and let it sit for an hour or as desired.

Peel the potatoes, slice them into rounds, wash them, and season with spices, tomato sauce, garlic, salt, and vinegar.

In a baking dish, add oil, then add the potatoes and chicken. Chop the onions and add them along with more oil. Mix everything together. Preheat the oven, cover the dish with aluminum foil, and bake for an hour. Then remove the foil, turn on the top heat, and bake for another hour, turning occasionally. Enjoy!
