Building the Flavor Base
Heat olive oil in a large pot over medium heat until it shimmers slightly.
Add chopped onions, carrots, celery, and lemon peel strips.
Sauté for 8-10 minutes, stirring frequently, until vegetables soften and become translucent.
Add minced garlic and cook for 1 minute until fragrant.
Adding Broth and Main Ingredients
Pour in 8 cups of vegetable broth and bring to a rolling boil over high heat.
Add rinsed chickpeas, orzo pasta, salt, pepper, and dried oregano.
Reduce heat to maintain a steady simmer.
Cook uncovered for 10 minutes until orzo reaches al dente texture.
Reduce heat to low.
Tempering the Eggs
In a large bowl, whisk together whole eggs, egg yolks, and fresh lemon juice until completely combined.
Ladle out 3/4 cup of hot broth from the soup pot.
While whisking the egg mixture constantly with one hand, slowly pour the hot broth in with the other hand in a thin stream.
Continue whisking continuously in rapid circles to prevent scrambling.
Finishing the Soup
While gently stirring the soup pot, slowly pour the tempered egg mixture into the soup.
Add chopped kale and keep heat on low.
Cook for 5 minutes until broth thickens slightly and greens wilt.
Remove and discard lemon peel strips.
Stir in fresh dill right before serving.
Taste and adjust seasonings with extra salt or lemon juice as needed.
Ladle into warm bowls and garnish with additional dill and cracked black pepper.
