Sear the chicken breast fillets, diced bacon, onions and chopped spring onions with a little butter in a large saucepan. Then take the fillets out of the pot briefly.
Add red wine to the saucepan and cook for 3 minutes. Add the broth, tomato pieces, a pinch of sugar, the tomato paste, the pepper and the bay leaves. Boil.
Add the chicken breast fillets to the broth and simmer on a low heat with the lid on for 30-40 minutes until the sauce is thick. Don`t forget to stir in between.
Prepare the mushrooms and add to the mixture and cook for another 5 minutes. Season to taste with salt and pepper.
Serve hot in a deep plate, with a baguette or bread roll, and sprinkle with parsley.
