Asparagus Egg Drop Soup

In a large saucepan, heat the oil. Add the onion and cook over moderate heat until softened, 8 minutes. Pour in the broth and bring to a simmer. Add the asparagus and cook until just tender, 3 minutes.

In a small bowl, whisk the eggs and season with salt and black pepper. Slowly pour the eggs into the simmering broth, stirring gently and constantly, until cooked, about 30 seconds. Season the soup with salt and pepper. Ladle the soup into bowls and top with the shaved Pecorino.
