Using a
food processor or an immersion blender, pulse chopped kale, toasted cashew nuts, salt, black pepper, garlic and Parmesan cheese (if using) until smooth. Gradually add oil until you like the consistency. Add more oil or more cashew nuts to adjust the consistency. Serve with pasta, bread, salads, sandwiches, potatoes, roasted or fresh vegetables, eggs, fish, soups, beans or anything else you like. Enjoy!
