A wholesome, deeply comforting soup crafted from slow-simmered stock, aromatic garden vegetables, and fresh herbs, served with crusty bread.
Bring the stock to a boil and add the fish balls; simmer 5 minutes.
Cook the noodles in a separate pot until just tender, then drain.
Blanch the choy sum in the noodle water for 1 minute.
Divide the noodles and greens between bowls.
Ladle over the hot broth and balls and top with soy sauce, pepper, fried shallots, and spring onions.
