Preheat the oven to 400˚F.
Spread softened butter on the French bread halves and place on a baking sheet. Bake for 5 minutes to toast.
While the bread is toasting, add chicken, Head Country Original BBQ Sauce, garlic, and red onion to a large bowl. Stir together until everything is evenly coated.
Spread the chicken mixture on each half of the bread, dividing the mixture evenly between the two. Sprinkle both halves with both cheeses evenly.
Bake for 8 to 10 minutes, until warm and gooey. To get that browned top, stick it under the broiler set to High for 1 minute.
Drizzle with bbq sauce and a sprinkle of parsley before serving.
