Peel onions and garlic. Chop onions coarsely, garlic finely. Wash the chicken meat, dab dry and cut into approx. 2 cm cubes. Heat 2 tablespoons of olive oil in a pan with a high rim.
Fry the diced chicken on a high heat for about 4 minutes until golden brown all around. Add onions and garlic and stir-fry for about 4 minutes. Add tomatoes and stock. Bring to the boil and stir in vinegar, sugar and tomato paste.
Add rosemary and laurel. Cover and braise over medium heat for about 35 minutes. Cook the last 15 minutes in the open pan, stirring occasionally. Season with salt and pepper. Stir in 1 tablespoon of olive oil.
Serve the braised chicken with the sauce. Sprinkle with parsley. Flatbread tastes good with it.
