Ingredients:

• 1 ½ pounds chicken tenderloins (cut thick ones in half lengthwise)
• White or whole wheat pita bread
• Crumbled feta cheese
• Tzatziki Sauce (store bought or homemade)
• Iceberg lettuce

For the Marinade:

• ½ cup olive oil
• Juice of one lemon
• 1 teaspoon salt
• ¼ teaspoon cracked black pepper
• ½ teaspoon crushed red pepper flakes
• 1 tablespoon minced garlic
• ½ teaspoon garlic powder
• 1 tablespoon Herbs de Provence (or Italian seasoning, see note)

For the Cucumber Salad:

• ½ cucumber, sliced or chopped
• ½ cup cherry tomatoes, halved
• ¼ red onion, thinly sliced
• 1 tablespoon freshly squeezed lemon juice
• Salt and pepper, to taste
• Pinch of fresh dill, optional

Instructions:

1. Whisk together all the marinade ingredients in a bowl until well combined.
2. Place the chicken tenderloins in the marinade, ensuring they are coated. Cover tightly and refrigerate for at least 30 minutes (or overnight).
3. While the chicken is marinating, prepare the cucumber salad by combining sliced cucumber, halved cherry tomatoes, thinly sliced red onion, freshly squeezed lemon juice, salt, and pepper. Add a pinch of fresh dill if desired. Set the salad aside.
4. Use tongs to transfer the marinated chicken to a preheated cooking surface (grill or skillet). Cook the chicken for 5-6 minutes on each side over medium heat until cooked through.
5. Assemble the pitas by placing pita bread on a plate or clean surface. Fill each pita with a layer of green-leaf lettuce, cooked chicken, the cucumber salad, crumbled feta cheese, and a dollop of homemade Tzatziki sauce.
6. Fold the pita over like a sandwich or roll it up for a delightful Mediterranean treat.
7. Enjoy the vibrant flavors and textures of your Mediterranean Grilled Chicken Pitas with Cucumber Salad!
