Place a large sauté pan over medium heat. Add the vegetable oil and sauté the onions and mushrooms until softened and starting to brown (about 8 minutes).
Deglaze the pan with the white wine, and add the cranberries. Simmer until most of the liquid has evaporated (about 2 minutes).
Stir in the turkey, Dijon mustard, and sour cream. Remove from heat.
Adjust seasoning to taste. Divide the noodles between 6 bowls and top with stroganoff mixture. Sprinkle with parsley.
