Kale is one of the trendiest vegetables these days, but it's still possible to serve it in a surprising way: grilled. Smoky and with a touch of crunch, hearty lacinato leaves are a delightful, if unusual, vehicle for a vinaigrette made with crisped bacon, shallots, and apple cider vinegar. It's a killer side dish you'll want to nestle alongside your potato salad and hamburgers at your next BBQ.
