Fry the onion in oil until lightly browned, add garlic then carrots then chicken stock and bring to boil. Once boiling, pop in your dumplings, and leave the little blobs for 5 minutes undisturbed until they are fully whitened. Then add your zucchini and cook for a further 3 minutes. Turn off the heat and pop in your corn and spring onions. Salt to taste. You are done.
