Gluten-free shepherd's pie is a favorite fall comfort food. Ground turkey is browned with onion, garlic, and cilantro before it is topped with creamy mashed potatoes. To achieve the design you see on restaurant made shepherd's pies, drag the tines of your fork across the surface of the mashed potatoes in a swirled motion. When the dish is baked, the browned surface will depict the pattern. This dish can also be made into individual portions by using ramekins.
