Bring a large pot of salted water to a boil. Add chicken breasts and simmer for 15-20 minutes until fully cooked.

In the same pot, add bow tie pasta and cook for 10-12 minutes until al dente. Drain and cool pasta under cold water.

In a large mixing bowl, combine chicken, celery, and green onions. Toss to mix.

In a medium measuring cup, whisk together mayonnaise, lemon juice, pepper, and parsley until smooth.

Pour dressing over chicken mixture and toss gently. Fold in grapes, pasta, and almonds.

Transfer to a serving bowl, garnish with pepper, and chill for 30 minutes before serving.
