For a tangier slaw, add a splash of apple cider vinegar along with the lemon juice. Adjust the amount of Sriracha to control the heat level; start with a smaller amount and add more to taste. For a vegan option, substitute the mayonnaise with a plant-based alternative. The slaw can be made a day in advance, allowing the flavors to fully develop. However, the cilantro is best added just before serving to prevent it from wilting.
