Sauté Veggies: Chop 1 onion, 1 carrot, 1 rib celery, and 2 cloves garlic in a food processor or with a knife.Sauté them in a large pot or Dutch oven with 1 leek (rinsed and sliced) in 2 tablespoons extra virgin olive oil oil for 5–10 minutes until soft.
Add Flavor: Stir in 2 tablespoon tomato paste and ½ teaspoon dried rosemary. Cook 1 minute to coat the vegetables and deepen flavor.
Simmer: Add 4 cups vegetable broth, 2 cans chickpeas (drained), 1½ pounds potatoes (diced), and 1 can crushed tomatoes. Season with ¾ teaspoon salt, pepper, and red pepper flakes. Simmer 20–30 minutes, until the potatoes are tender.
Finish & Serve: Taste and adjust seasoning. Thin with extra broth if needed. Serve hot with crusty bread or cooked grains. For extra flavor, top each bowl with grated parmesan or crumbled feta before serving.
