Heat olive oil in a large pot over medium heat. Add diced onion, carrots, and celery, cooking for 5 minutes until vegetables begin softening and releasing their natural aromas.

Stir in minced garlic and cook for exactly 1 minute until fragrant. Add cumin, paprika, salt, pepper, and bay leaf, mixing constantly so the spices toast slightly and activate their flavors.

Pour in the vegetable broth and canned diced tomatoes with their juices. Bring the mixture to a gentle boil, then reduce heat to medium-low and simmer for 8 minutes to develop the base flavors.

Add the drained chickpeas to the pot and stir well to distribute evenly throughout the broth. This chickpea soup will become creamier as the legumes break down slightly during cooking, creating natural body without heavy cream.

Simmer for an additional 5 minutes until chickpeas are heated through and flavors meld together beautifully. The broth should reduce slightly, intensifying all the Mediterranean spice notes.

Remove from heat and stir in fresh spinach and lemon juice. The spinach wilts immediately in the residual heat, adding vibrant color and fresh iron to balance the earthiness of the legumes.

Taste and adjust seasonings as needed, adding more salt, lemon juice, or spices to your preference. Let the pot sit for 2 minutes before serving to allow flavors to fully integrate.
