How to Make It
Working in batches, place the fennel, celery, scallions, onion, garlic, and red peppers in the bowl of a food processor and pulse until finely chopped but not pureed.
Transfer to a large glass or plastic bowl and stir in the tomatoes, oil, salt, black pepper, tomato juice, lemon juice, and hot sauce, if using.
Cover and refrigerate for at least 2 hours and up to 6. Serve chilled with the lime wedges.
