Preheat oven to 350°
Place trimmed chicken in a 9"x13" baking dish sprayed with cooking spray.
In a saute pan, heat oil and add garlic, celery, carrots and onions. Cook over medium-high heat until onions are translucent. About 5 minutes.
In a large bowl, melt butter in microwave. Combine remaining ingredients and mixture from saute pan to melted butter. Pour over chicken.
Cover with foil and bake for 35-40 minutes (depending on how thick the chicken breasts are) until cooked through. Remove chicken and slice then return back to dish or other serving dish and cover with vegetables and sauce.
