How to Make It
In a medium pot, bring the chicken stock to a simmer over moderate heat. In a small bowl, whisk together the eggs and cheese. Slowly add the egg mixture into the hot stock, stirring constantly, until the eggs are just set, about 1 minute. Stir in the chicken and peas and simmer until heated through, about 2 minutes. Add the spinach and basil and cook until just wilted, about 1 minute. Season with salt and pepper and serve.
