Heat olive oil in a large saucepan over medium heat. Cook chorizo for 2 minutes or until golden. Transfer to a plate. Add onion and garlic to the same pan and cook for 3 minutes or until onion softens. Increase heat to high, add potatoes and cook for a further 3 minutes or until potatoes start to soften.
Add 1.75L water and bring to the boil. Reduce heat to medium and cook for 20 minutes or until potatoes are very tender.
Using a handheld blender, purée soup until roughly blended. Return pan over high heat, stir in chorizo, 2 tsp salt and 1 tsp pepper and cook for 2 minutes or until heated through.
Stir in cavolo nero, cover, and stand for 5 minutes or until wilted. Serve with crusty bread.
