Heat 1 tablespoon of oil in a large pot, add in the onions, and sauté for 2–3 minutes. Then add in the aubergine and peppers. Fry, stirring every now and then, for about 5 minutes.
Remove from the pan and set aside.
Add in the remaining tablespoon of oil into the same pot, and fry the chicken until browned and cooked through, for about 8 minutes.
Next, add in the garlic and cooked vegetables. Season with salt, pepper, oregano, and hot paprika.
Pour in hot chicken stock, and bring to a boil. Reduce the heat to low.
Cover and simmer for 15 minutes. In the end, add the chopped cherry tomatoes and tomato paste.
Add the flour directly through a sieve. Mix well and cook for another 1-2 minutes, until the sauce thickens. Garnish with chopped parsley and serve.
Serving suggestions: roasted buckwheat groats, rice, potato, or pasta.
