Meanwhile, in a large nonstick skillet heat the remaining 1 teaspoon olive oil over medium heat. Add sausage, onion, and garlic. Cook about 10 minutes or until sausage is browned and onion is tender, stirring to break sausage apart. Add kale, raisins, and broth; stir to combine. Cover; cook for 8 to 10 minutes or until kale is wilted, stirring occasionally. Remove from heat. Stir in cheese and the remaining 1/4 teaspoon pepper.
