Creating Italian Grinder Chicken Salad is a straightforward process if you follow these steps:

1. Cook Chicken: If not already cooked, grill or bake the chicken breast until fully cooked and no longer pink in the center. Allow it to cool before shredding.
2. Prepare Veggies: While the chicken is cooking, chop the romaine lettuce, halved cherry tomatoes, sliced cucumbers, diced red onion, and black olives.
3. Mix Dressing: In a small bowl, whisk together mayonnaise, red wine vinegar, Dijon mustard, olive oil, Italian seasoning, garlic powder, salt, and pepper until smooth.
4. Combine Ingredients: In a large bowl, add the shredded chicken and the chopped vegetables.
5. Add Dressing: Pour the dressing over the chicken and vegetables. Gently stir to combine, ensuring everything is evenly coated.
6. Taste and Adjust: Sample the salad and adjust seasoning if necessary. Add more salt, pepper, or spices according to your taste.
7. Chill: For the best flavor, refrigerate the salad for at least 10 minutes before serving.
8. Serve: If desired, sprinkle grated Parmesan cheese on top before serving. Garnish with fresh basil for an extra touch.

Following these simple steps will help you create a delicious Italian Grinder Chicken Salad that everyone will enjoy.
