Wash the turnip greens and tear them into pieces. Boil them for 2-3 minutes in salted boiling water. Drain and keep to one side.
Sweat the garlic with the chili pepper and a few tablespoons of oil in a saucepan, add the sausage skinned and cut into pieces and brown it evenly. Pour in the white wine, let it evaporate and add the peeled tomatoes chopped into pieces and cook for 15 minutes.
