Just when the thought of another tossed green salad leaves you feeling bored, this recipe will offer fresh inspiration. Sliced apples and cubed mango is a refreshing change of pace from other fruit pairings, while walnuts and cheese make delightful toppings. Arugula is a peppery addition to the usual lettuce mix, and to allow all these flavors to shine through the "dressing" is simply olive oil and fresh lemon juice.
