Two healthy green salad dressings: tahini-lemon and avocado-herb

Instead of mayonnaise or store-bought dips, homemade green dressings can enhance salads without undermining their nutritional value. The first dressing is based on tahini, lemon juice and garlic; the second uses avocado blended with fresh herbs. Both can be kept in the fridge and work with a variety of vegetables, from mixed leaves to broccoli and asparagus.
