Avocado and Papaya Salad with Mango Vinaigrette

Mango and raspberries go into the dressing, which is a little tart and fruity, with the color of a sunrise. A peppery green, like watercress, makes a good contrast to the sweet, smooth fruit, and the glossy dark green leaves set off the fruit and sauce beautifully. With each salad arranged on its own plate, this makes a rather special beginning to a meal.
