Heat a skillet over medium heat and add the olive oil. Stir in the onion and cook for 5 minutes, until slightly softened. Stir in the garlic and cook for a few seconds. Add in the chorizo, breaking it up with a wooden spoon into tiny crumbles. Season it with the salt, pepper and paprika. Cook the sausage, stirring often, until its browned and golden, about 6 to 8 minutes. Transfer the contents of the skillet to a bowl.
