How to Make It
Heat oil in a large stockpot over medium heat. Add garlic, carrots, and leek to pan; cook, stirring frequently, for about 10 minutes or until vegetables are soft and aromatic. Add chicken stock to vegetables and increase heat to medium-high; bring to a boil. Add rice and reduce heat to medium-low; cook, stirring occasionally, until rice is nearly done, about 20 minutes.
Whisk together lemon juice and eggs in medium bowl. Slowly pour 1 cup of hot broth into egg mixture, whisking constantly, then pour egg mixture back into pan, stirring. Add dill, spinach, chicken, and salt; allow spinach to wilt and soup to heat back up, about 10 minutes. Sprinkle with black pepper, if desired. Serve.
