Ziti with Chicken, Spinach and Walnuts

In large nonstick skillet, toast walnuts over medium heat, shaking pan occasionally, until fragrant, about 5 minutes. Remove from pan and set aside.

Slice chicken thinly across the grain; sprinkle with half each of the salt and pepper. In same skillet, heat oil over medium-high heat; saut?hicken, in 2 batches, until golden and no longer pink inside, about 4 minutes. Using slotted spoon, transfer chicken to bowl.

Add garlic, spinach and remaining salt and pepper to pan; cover and cook over medium heat just until spinach begins to wilt, about 1 minute. Return chicken and any accumulated juices to pan. Stir in chicken stock and vinegar; bring to simmer.

Meanwhile, in large pot of boiling salted water, cook pasta until tender but firm, 8 to 10 minutes. Drain and return to pot. Add chicken mixture and walnuts; toss to coat. Serve sprinkled with Parmesan cheese.
