Cook the Turkey: In a large skillet, heat the olive oil over medium heat. Add the ground turkey and Mediterranean seasoning. Cook for about 5-7 minutes, breaking it apart with a spatula, until fully cooked and browned. Season with salt and pepper to taste.
Prepare the Salad: While the turkey is cooking, in a bowl, combine the cherry tomatoes, cucumber, red onion, feta cheese, and Kalamata olives. Gently toss together and set aside.
Warm the Pitas: If desired, warm the whole wheat pitas in a toaster or on a skillet for a minute or two until soft and pliable.
Assemble the Pitas: Place a generous scoop of the cooked turkey into each pita. Top with the Mediterranean salad mixture and drizzle with tzatziki sauce.
Garnish and Serve: Sprinkle with fresh parsley for a burst of color and aroma. Serve immediately and enjoy your delicious, healthy meal!
