In a large stockpot over medium heat, add the olive oil. Saut? onions until soft, about 5 minutes. Add chicken broth, lamb, parsley and dill. Bring to a boil, reduce heat, cover and simmer for about 1 hour.

Add rice and continue simmering until soft, about 20 minutes.

In a medium bowl, beat the egg yolks and lemon juice until frothy. Gradually add 1 to 2 cups of hot soup to egg mixture, beating vigorously with a whisk to keep eggs from curdling.
