Clean and wash the vegetables. Dry them, cut them into small pieces and then arrange them in a bowl. Use the following ingredients to make a dressing sauce in a separate bowl : a pinch of salt, some mustard and Balsamic Vinegar from Modena. Stir carefully while adding the olive oil until you get a soft cream sauce. Dress the salad with this sauce and stir very gently. Allow some minutes to rest and serve.
