How to Make It
Heat a 6-quart pressure cooker over medium-high heat. Add oil to pan; swirl to coat. Add onion; sauté 3 minutes. Add garlic and chorizo; sauté 2 minutes. Stir in 2 1/2 cups water, broth, chickpeas, and bay leaves. Close lid securely; bring to high pressure over high heat. Adjust heat to medium or level needed to maintain high pressure; cook 1 hour. Remove from heat; release pressure through steam vent, or place cooker under cold running water to release pressure. Remove lid. Discard bay leaves. Add escarole and remaining ingredients, stirring just until escarole wilts. Serve immediately.
