Meanwhile, while the broth simmers, cook your wontons, noodles and pak choy. Bring a large saucepan of water to the boil. Working in batches, add the wontons and cook for 3-4 minutes or until they float to the surface and are cooked through. Remove with a slotted spoon and divide among serving bowls.
Return the water to the boil. Add the noodles and cook per packet instructions, usually around 3-5 minutes, adding the pak choy in the last 1 minute. Drain into a colander then divide noodles and greens among serving bowls (with the wontons).
Ladle the chicken broth over the wontons, noodles and greens. Garnish with spring/green onions and fried shallots. Serve with Chilli Garlic Crunch Oil, Chilli oil or sliced red chilli on the side if desired.
