PLACE kale in food processor along with nuts, lemon juice, garlic, salt and pepper. Pulse until kale is finely chopped. Add cheese; pulse until incorporated. Drizzle in oil and continue to pulse until pesto reaches desired consistency.
PREPARE pasta according to package directions, reserving ½ cup cooking water. Toss pesto, pasta and ¼ cup of the cooking water in large bowl to coat. Thin with additional water, if desired. Top with additional nuts, if desired.
Cook’s Tip: To add a little heat, add a pinch of crushed red pepper flakes. To toast the nuts, place nuts in a medium, dry skillet over medium heat, stirring frequently, for 4 minutes or until fragrant.
