How to Make It
Heat 1 tsp. oil in a large saucepan over medium heat. Add onion and cook until softened, about 3 minutes. Add fennel seeds, rosemary, tomatoes, chickpeas, wine, and broth and cook, covered, until boiling.
Meanwhile, cut fish into 1-in. chunks and add to boiling broth. Reduce heat and simmer until fish is cooked through and pulls apart when poked with a fork, about 3 minutes. Remove rosemary sprig, season with salt and pepper, and spoon into bowls. Drizzle each serving with oil, sprinkle with parsley, and serve with warm, crusty bread.
