With slotted spoon, transfer chorizo to bowl; set aside. To drippings in skillet, add fennel, onion, and garlic, and cook about 4 minutes or until fennel softens slightly. Add half of tomatoes and 4 tablespoons parsley and cook 1 minute Add rice, stirring to coat well. Pour in warm broth; heat to boiling over high heat.
