Begin by preparing your fresh ingredients for the Mediterranean Chicken Salad. Dice the cucumber, making sure to remove the seeds for optimal texture. Finely mince the red onion and chop the fresh dill. Crumble the feta cheese and chop the olives. Place all these ingredients in separate bowls to make mixing easier as you go.

In a large mixing bowl, whisk together the mayonnaise and Greek yogurt until smooth. Gradually add the freshly squeezed lemon juice, Dijon mustard, garlic powder, and Greek seasoning, mixing thoroughly to ensure a creamy, well-blended dressing.

Drain the canned chicken thoroughly and gently add it to the dressing mixture. Using a spatula, fold the chicken into the dressing until each piece is coated.

Fold in the prepared cucumber, minced onion, crumbled feta, chopped olives, and fresh dill into the chicken mixture.

Transfer the completed Mediterranean Chicken Salad to an airtight container and refrigerate for at least 30 minutes.
