Heat oil in a large saucepan over medium heat. Add mushrooms, celery, carrots and shallots and cook, stirring, until softened, about 5 minutes. Add flour, salt and pepper and cook, stirring, for 2 minutes more.

Add broth and bring to a boil, scraping up any browned bits. Add rice and reduce heat to a simmer. Cover and cook until the rice is tender, 5 to 7 minutes. Stir in turkey (or chicken), sour cream and parsley and cook until heated through, about 2 minutes more.

Ingredient note: Quick-cooking or instant wild rice has been parboiled to reduce the cooking time. Conventional wild rice takes 40 to 50 minutes to cook. Be sure to check the cooking directions when selecting your rice--some brands labeled "quick" take about 30 minutes to cook. If you can't find the quick-cooking variety, just add cooked conventional wild rice along with the turkey at the end of Step 2.

Tip: To poach chicken breasts, place boneless, skinless chicken breasts in a medium skillet or saucepan. Add lightly salted water to cover and bring to a boil. Cover, reduce heat to low and simmer gently until chicken is cooked through and no longer pink in the middle, 10 to 12 minutes.
