Substituting thick, tangy Greek-style yogurt for mayonnaise lightens up this recipe considerably without compromising flavor or consistency. This is a great way to make lunch fare from the leftover roasted chicken, or you can use a grocery store rotisserie bird as well. Grated carrots add crunch and sweetness (not to mention Vitamin A and fiber!). Grating the onion is faster than chopping, and results in onion flavor without the big chunks. Serve on whole grain bread or pita, or on a bed of greens, or by itself! Recipe courtesy of Sara Talcott.
