Fry the chicken breasts in oil in a large saucepan. Add the bacon and fry. Chop the onions, soup greens, bay leaf, thyme and marjoram, add them to the saucepan and fry them with them.
Blanch the tomatoes, peel them, cut them into small pieces, add them to the pan and fry them with them. Put the red wine, cognac, salt and pepper in the pot and simmer with the lid on for approx. 1 hour over a low heat.
