In a stock pot, warm the sesame oil over medium heat. Add ginger and garlic, and saute for one minute.
Add the onion and carrot, and continue to cook until the onion becomes translucent and carrots become tender, about 5-7 minutes. Add a little water if it starts to stick to the bottom of the pan.
Add the broccoli, bok choy, baby corns, water chestnuts, bouillon cubes and 6 cups of water. Cover and continue to cook for 10-15 minutes, until the vegetables become tender.
Once the veggies are cooked, bring soup to a boil, and add the frozen dumplings. Cover, and continue to boil for about 5 minutes or until the dumplings are cooked. Remove from heat, and serve. Garnish with hot chili oil and sesame seeds, if you like.
