Begin by preparing your fresh ingredients. Dice the cucumber, finely mince the red onion, chop the dill, and crumble the feta.

In a mixing bowl, whisk together mayonnaise and Greek yogurt until smooth. Gradually add lemon juice, Dijon mustard, garlic powder, and Greek seasoning.

Add the drained canned chicken to the dressing mixture, gently folding it in until well coated.

Fold in the cucumber, minced red onion, feta, and olives until combined without mashing the feta.

Allow the salad to chill in the refrigerator for at least 30 minutes for the best flavor.
