For a smoky flavor, add a few wood chips to your grill. Feel free to experiment with different types of barbecue sauce to customize the flavor profile. If you don't have a grill, you can bake the sweet potatoes in a preheated oven at 400°F (200°C) for approximately 1 hour, or until tender. The cilantro cream can be made ahead of time and stored in the refrigerator until ready to use. Consider adding a pinch of red pepper flakes to the BBQ beans for a touch of heat.
