Barbecue-flavored burgers zing with zesty chipotle Cheddar cheese and crispy crowns of fried red onion rings. For sides that steal the show, serve tri-colored herb-roasted potatoes and grilled summer-vegetable kabobs that are oh-so tasty, but a cinch to prepare. And for a spectacular firework finish, Star Tarts and Flag-Waving Cookies are guaranteed to produce wows of delight from patriots of all ages.
