Warm the olive oil in a large pot over medium heat.
Soften the onion, carrots, and celery with a pinch of salt for 5–7 minutes, stirring occasionally.
Stir in the garlic, oregano, cumin, and turmeric. Cook until fragrant, about 1 minute.
Add the chicken and cook, stirring, until lightly opaque on the outside, 3–4 minutes.
Pour in the broth. Bring to a boil, then reduce heat and simmer gently for 15 minutes.
Stir in the chickpeas and cook 5 minutes more to warm through.
Off the heat, add lemon juice and zest. Season with salt, black pepper, and red pepper flakes to taste.
Fold in parsley and spinach until the greens wilt. Rest 2 minutes, then ladle into bowls.
