01 - Heat olive oil in a large soup pot over medium heat. Add onion, carrots, and celery. Sauté for 5–6 minutes until softened and fragrant.
02 - Add minced garlic and diced zucchini to the pot. Cook for 2 minutes, stirring frequently to prevent garlic from burning.
03 - Stir in rinsed barley, dried thyme, oregano, bay leaf, vegetable broth, and water. Increase heat to bring mixture to a rolling boil.
04 - Reduce heat to low, cover, and simmer for 30 minutes. Stir occasionally to prevent barley from sticking to the bottom of the pot.
05 - Add drained chickpeas to the simmering soup. Continue cooking for 15–20 minutes, until barley is tender and chickpeas are heated through.
06 - Remove and discard bay leaf. Stir in lemon zest, lemon juice, and chopped fresh dill. Season with additional salt and pepper as needed.
07 - Ladle hot soup into bowls. Garnish with additional fresh dill and lemon wedges if desired. Serve immediately while hot.
