Tuscan Lemon Herb Vinaigrette

"Here is a WW vinaigrette that will cut down the number of calories, with the introduction of chicken broth with no loss of flavor beating away chemicals and fillers found in store-bought dressings. This dressing needs to marinate overnight to allow the full flavor of the basil, lemon zest, garlic, and oregano to develop. Drizzle over a salad of greens, vegetables, rice, etc.. WW value: 1 point, 1 1/2 tablespoons per person."
