Surprise Barbecue Hot Dogs

Preheat the oven to 400 degrees F (200 degrees C).

Melt butter in a saucepan over medium heat. Stir in onion and brown sugar and cook until onion is soft but not yet brown, about 5 minutes. Add ketchup, mustard, and Worcestershire sauce; bring to a simmer. Remove from heat.

Cut a slit through each hot dog and fill with cubes of cheese food. Place dogs in buns and cover meat with onion sauce, about 3 tablespoons each. Wrap in aluminum foil.

Bake in the preheated oven until piping hot throughout, about 15 minutes.
