These classic vegetable dumplings are filled with a delicious mixture of finely chopped cabbage, carrots, mushrooms, and green onions. The filling is seasoned with soy sauce, ginger, and garlic for a burst of flavor. The dumplings are then steamed or pan-fried to perfection, resulting in a crispy exterior and a juicy, flavorful interior. Serve them with a dipping sauce made from soy sauce, rice vinegar, and sesame oil for a delightful appetizer or main course.
