Prepare the wild rice: Toast pecans until fragrant in a small pan over medium heat. Chop and reserve.
Bring a small pot or kettle of water to a boil. Place cranberries into a small bowl and cover with boiling water to reconstitute. Let stand until softened then drain and chop.
In a medium saucepot, melt butter over medium heat and add the celery, apple, onion, thyme, salt and pepper. Saut to soften, 7-8 minutes. Add rice and toast a minute or two; add stock and water, and bring to a boil. Reduce heat to simmer, cover and cook 30 minutes. Uncover and cook 15 minutes more until tender and fluffy. Drain and add chopped cranberries, scallions, parsley and reserved pecans. Adjust salt and pepper to taste.
Preheat oven to 350F.
Butterfly chicken breasts open by cutting through the breasts lengthwise to open the breasts like a book. Season the chicken with salt, pepper and thyme. Fill the chicken breasts with chutney and cheese. Close the chicken breasts back over to cover the filling.
Heat a large, ovenproof skillet over medium-high heat with EVOO, 2 turns of the pan. Brown stuffed chicken on both sides and transfer to oven to finish cooking through, 15-20 minutes. Remove chicken to plate and cover with foil.
For the gravy, melt butter in the skillet and whisk in flour. Cook 1 minute then add stock and season with black pepper and whisk in Worcestershire, Dijon and maple syrup. Let thicken to coat spoon and adjust seasoning.
Serve chicken topped with gravy, with wild rice alongside.
