Cozido à Portuguesa is a traditional Portuguese stew that features a variety of meats, vegetables, and sausages. Using a food processor can help in the preparation of the stew. Start by pulsing onions, garlic, and tomatoes in the food processor until finely chopped. Sauté the mixture in olive oil until fragrant. In a separate pot, cook a selection of meats, such as beef, pork, and chicken, until tender. Shred the cooked meats using the food processor. Add the shredded meats to the sautéed mixture and stir well. Then, add a variety of vegetables, such as carrots, cabbage, and potatoes, to the pot. Let the stew simmer until all the flavors meld together. Serve the Cozido à Portuguesa hot, garnished with fresh herbs. It's a hearty and flavorful dish that is perfect for gatherings and special occasions.
