Caldo Verde is a traditional Portuguese soup made with kale, potatoes, onions, garlic, and chorizo. Using a food processor can help speed up the preparation process. Start by pulsing the onions and garlic in the food processor until finely chopped. Sauté the chopped onions and garlic in olive oil until translucent. Meanwhile, use the food processor to slice the potatoes into thin rounds. Add the sliced potatoes to the pot and cook until tender. In a separate pot, blanch the kale leaves and then chop them finely using the food processor. Add the chopped kale to the potato mixture and simmer until the flavors meld together. Serve the Caldo Verde hot, garnished with slices of chorizo. It's a hearty and comforting soup that is perfect for colder days.
