How to Make It
Preheat oven to 325°.
Arrange grapes in a single layer on a wire rack set in a jelly-roll pan coated with cooking spray. Bake at 325° for 1 hour and 15 minutes or until slightly shriveled. Cool on wire rack.
While grapes bake, combine oil and rosemary in a small microwave-safe dish; microwave at HIGH 40 seconds. Remove from microwave, and let stand 20 minutes. Strain through a sieve into a bowl; discard solids.
Place kale in a large bowl; massage kale with hands until tender and dark green. Add strained oil, vinegar, and salt; toss to coat. Add roasted grapes, chicken, lemon juice, green onions, and celery; toss. Top with cheese.
