Frozen Yogurt with Mango-Lime Topping

Mangoes are available year-round in the United States. My favorite mango is the Kent, which is creamy and flavorful. This recipe calls for key limes, but regular limes work, too. You can make the mango topping a day in advance and prepare the dessert just before serving. Add bananas to the bottom of the serving dish to make it even more special.
