TIPS FOR GRILLING FRUIT: Did you know that you can grill just about any fruit? As long as they’re firm and not overripe, that is. Some of my favorite fruits to grill are peaches, plums, pineapple, bananas, mangoes and many more! In most cases, you’ll get best results by grilling the fruit skin on. But if you’re grilling pineapple or watermelon, you need to remove the tough outer skins. Grilling fruits over high heat boosts their natural sweetness and adds great flavor.
