Made in the spring when both morel mushrooms and vidalia onions are in season (and, sometimes, the rare heirloom tomato such as a Cherokee Purple), this dish can be a nice change from regular beef stroganoff. It's important to note that when I came up with this recipe, the only wine I had on-hand was "off" so I left it out. Honestly? I didn't notice the difference and was able to taste the lamb much more. Don't use fat-free sour cream; you need some fat (I go for low-fat) in order for the sauce to form and get thick. This makes 6, light servings (fairly small), good for a brunch or light supper.
