Chicken Stew with Olives and Mushrooms

Clean and cut the chicken into pieces. In a pot, fry the bacon, cut into pieces, then add the mushrooms, the sliced olives, the tomatoes — chopped or grated — and 4-5 potatoes, also cut up. Finally add the chicken meat. Pour in 1/2 cup of cognac and as much water as needed, and leave it to simmer until the meat is tender.
