To prevent the spring roll wrappers from sticking together, keep them covered with a damp cloth while you are working. Feel free to customize the fillings with other vegetables such as shredded carrots, bell peppers, or lettuce. For a spicier kick, add a drizzle of sriracha or a pinch of red pepper flakes to the filling. If you prefer a different dipping sauce, consider using hoisin sauce, sweet chili sauce, or a mixture of soy sauce and rice vinegar.
