Spicy Potato & Kale Soup

Heat a large saucepan over medium heat. Add chorizo and cook, stirring, until browned, about 2 minutes. Transfer the chorizo to a paper towel-lined plate; wipe out the pot.

Heat oil in the pot over medium heat. Add onion and cook, stirring occasionally, until softened, about 2 minutes. Add broth, water, potato and garlic; increase the heat to high and bring to a boil. Reduce to a simmer, cover and cook, stirring occasionally, until the potato is tender, 6 to 9 minutes. Lightly mash the potato with a wooden spoon. Add kale, a handful at a time, waiting until it has wilted before adding more. Adjust heat to maintain a simmer and cook, stirring occasionally, until the kale is tender, about 5 minutes. Add the reserved chorizo and season with pepper.
