Precook the bacon in advance for faster assembly.Use pre-sliced cabbage to save time on preparation.Brush the melted butter mixture on the cabbage using a basting brush for even distribution.Place the bacon and onions in a separate dish to allow guests to customize their servings.For a smokier flavor, consider using a smoker instead of a barbecue grill.Experiment with different seasonings, such as paprika or chili powder, to add a kick of flavor.
