Trippa alla Pennese is a traditional dish originating from Penne in Abruzzo. The dish is usually made with a combination of tripe, olive oil, onions, celery, tomatoes, pecorino, parsley, bay leaves, mint, bell peppers, and marjoram. The tripe is cleaned, boiled in salted water, drained, cut into strips, and then added to the pan with sautéed onions and celery.
