Lots of recipes call for grilled, sweet onions.  Grilling the onions brings out the natural sugars and, with a bit of olive oil and balsamic vinegar, is a scrumptious addition to almost any grilled meal.  The challenge is to grill the onions without them falling through your cooking grills.  You can do this with a grill topper, a cast iron griddle OR for something more dramatic you can make onion lollipops.  Just skewer your onions before you grill them and put them right on your grill.  Voila, no more onion attrition!
