Cook Chicken: In a medium pot, bring salted water to a boil over high heat. Add the chicken and cook for 15-20 minutes until cooked through. Remove, drain, and cool slightly before chopping.

Cook Pasta: In another pot, bring water to a boil and add bow tie pasta. Cook for 8-10 minutes until al dente, then drain and rinse under cold water.

Combine Dry Ingredients: In a large bowl, combine chopped chicken, diced celery, and sliced green onions. Toss until evenly mixed.

Make Dressing: Whisk together mayonnaise, lemon juice, pepper, and parsley in a measuring cup until smooth. Adjust seasoning to taste.

Mix Salad: Pour dressing over the chicken mixture and stir gently until all ingredients are well coated.

Add Remaining Ingredients: Fold in cooked pasta, grapes, and almonds carefully to avoid breaking the pasta.

Serve: Transfer the salad to a serving bowl and sprinkle cracked pepper on top before serving.
