Avocado-Lime Ranch Dressing

This dressing is a Chick-fil-A copycat recipe. It has no sugar added, is half the calories of the original, and is made with buttermilk, avocado, fresh cilantro, spices and lime for a tangy, zesty twist on a classic salad dressing. Dairy-based salad dressings will last in the refrigerator for up to a week. Using freshly opened sour cream and buttermilk will help it last as long as possible. —Kelsey Reddick Smith, Knoxville, Tennessee
