Plump steamed dumplings with savory pork and vegetable filling make a protein-rich breakfast. A fresh, family favorite with delicate, juicy flavor.
Finely chop the cabbage, scallions, and ginger. Set aside.
In a large mixing bowl, combine ground pork, chopped vegetables, soy sauce, sesame oil, rice vinegar, salt, pepper, and the beaten egg. Gently mix until just incorporated, being careful not to overmix.
Place a dumpling wrapper on your palm, add 1 heaping tablespoon of filling to the center, then moisten the edge with water and fold to seal. Repeat with all wrappers.
Line a steamer basket with parchment or cabbage leaves to prevent sticking. Arrange dumplings in a single layer with space between each.
Steam dumplings over simmering water (medium heat) for 10–12 minutes, making sure the pork is cooked through and wrappers are translucent. Serve immediately while hot.
