If cooking on stove top: Saute onions, celery and carrots in butter 3-4 minutes. Reduce heat; add in flour-cook until it is bubbly. Add in broth, stirring constantly. Bring to boil; reduce heat. Add rice, turkey, cream, salt, pepper, garlic powder, etc. Simmer for about 20 minutes. Serve.
Another way to make this quicker, use store bought broth and shred up a rotisserie chicken or use pre-cooked turkey.
