You will be accused of committing fancy bun work when these easy to create Kaisers are set on your table filled with your preferred fillings. They'll think you slaved all day.
Line Dutch oven with foil and spray with non-stick cooking spray. Place turkey or roast beef in Dutch oven and liberally coat with barbecue sauce. Place over coals. Bake at 350°F until heated through following general Dutch oven directions.
This usually takes 20-30 minutes (cooking time is shortened because meat is already cooked). Place roast beef or turkey in your pre-baked Kaiser rolls.
