From a Sunset Magazine special edition, "Sunset Weeknight." I haven't tried it yet, but it sounds tasty. Suggested accompaniments include purchased (fresh or frozen) potstickers or egg rolls and cabbage slaw with Asian dressing.
Rinse chicken and pat dry. Slice crosswise into 1/8-inch thick strips. Combine with rice wine, 1/2 tsp sesame oil, and 1 tbsp cornstarch in a small bowl.
In a 3-4 quart nonstick pan over high heat, stir garlic and ginger in 1/2 tsp sesame oil for 10 seconds. Add chicken and stir-fry until no longer pink on surface, about 2 minutes.
Add broth; cover pan and bring to a boil. Add tofu and corn to broth and return to a simmer.
In a small bowl, combine remaining 2 tbsp cornstarch and 1/4 cup cold water until smooth. Add to soup; bring to boil, stirring constantly. Pour egg into soup, stirring gently for about 30 seconds to form thin strands of egg. Add remaining 1/2 tsp sesame oil, green onions, and season to taste with salt and white pepper. Ladle into bowls and serve.
