Allow bread rolls to come to room temperature and rise. When ready, take a bread roll and flatten it into a large disc shape in the palm of your hand. Spoon approximately two large tablespoons of barbecue into the middle of the bread roll. Carefully fold the bread roll around the filling to seal in the delicious barbecue. Pinch and seal the seams to keep the filling from bubbling out during baking. Place stuffed bun seam-side down in a 9x13 baking pan and repeat until all twelve have been filled. Cover and allow buns to rise for another hour. After buns have risen for an hour, heat oven to 350 degrees. Then, melt 1/2 stick of butter and add two tablespoons of honey. Stir to mix. Baste each bun with plenty of the honey butter mixture. Sprinkle sesame seeds over each bun. Bake at 350 for 25-30 minutes until golden brown.
