Step 1: Marinate the Chicken (The Flavor Foundation)

1. Prepare the Marinade: In a medium-sized bowl, whisk together the extra virgin olive oil, freshly squeezed lemon juice, minced garlic, dried oregano, smoked paprika (if using), salt, black pepper, and red pepper flakes (if using). Ensure it’s well combined.
2. Add the Chicken: Pat the chicken pieces dry with paper towels (this helps the marinade adhere better). Add the chicken pieces to the bowl with the marinade.
3. Combine Thoroughly: Toss the chicken gently but thoroughly, ensuring every piece is coated with the marinade.
4. Marinate: Cover the bowl tightly with plastic wrap or transfer the chicken and marinade to a resealable plastic bag. Refrigerate for at least 30 minutes to allow the flavors to penetrate. For best results and more tender chicken, marinate for 2-4 hours. You can even marinate it overnight for maximum flavor infusion, but be mindful that the lemon juice can start to “cook” the chicken slightly if left too long (more than 12 hours).

Step 2: Prepare the Tzatziki Sauce (Cool & Creamy Counterpart)

1. Prepare the Cucumber: Finely grate the cucumber using a box grater or food processor. Place the grated cucumber in a clean kitchen towel or several layers of paper towels. Squeeze firmly over the sink or a bowl to remove as much excess water as possible. This step is crucial to prevent a watery tzatziki. You’ll be surprised how much liquid comes out! Discard the liquid.
2. Combine Ingredients: In a separate medium bowl, combine the strained Greek yogurt, the squeezed grated cucumber, minced garlic, chopped fresh dill (or dried), lemon juice, extra virgin olive oil, salt, and pepper.
3. Mix Well: Stir everything together until well combined and creamy.
4. Chill: Taste and adjust seasoning if needed (more salt, lemon, or garlic?). Cover the tzatziki sauce and refrigerate for at least 20-30 minutes before serving. This allows the flavors to meld and deepen. Tzatziki tastes even better after an hour or two in the fridge.

Step 3: Cook the Chicken (Sizzle & Sear)

You have several options for cooking the chicken. Choose the one that suits you best:

• Option A: Pan-Searing (Stovetop)

  1. Heat a large skillet or frying pan over medium-high heat. Add a tablespoon of olive oil if needed (though the marinade often provides enough).
  2. Once the pan is hot (a drop of water should sizzle instantly), carefully add the marinated chicken pieces in a single layer. Do not overcrowd the pan; cook in batches if necessary to ensure proper searing rather than steaming.
  3. Cook for 5-8 minutes, turning occasionally, until the chicken is golden brown, slightly charred in spots, and cooked through (internal temperature should reach 165°F or 74°C).
  4. Remove the cooked chicken from the skillet and set aside.

• Option B: Grilling (Outdoor or Indoor Grill Pan)

  1. Preheat your grill (outdoor or indoor grill pan) to medium-high heat. If using an outdoor grill, lightly oil the grates. If using chicken pieces (not strips), consider using skewers for easier handling.
  2. Remove chicken from the marinade, letting excess drip off. Place the chicken (or skewers) on the hot grill.
  3. Grill for 6-10 minutes, turning halfway through, until grill marks appear and the chicken is cooked through (165°F or 74°C). Grilling imparts a wonderful smoky flavor.

• Option C: Baking (Oven)

  1. Preheat your oven to 400°F (200°C).
  2. Spread the marinated chicken pieces in a single layer on a baking sheet lined with parchment paper.
  3. Bake for 15-20 minutes, or until the chicken is cooked through and lightly browned (165°F or 74°C). You can switch to the broiler for the last 1-2 minutes for extra browning, but watch carefully to prevent burning.

Step 4: Rest the Chicken

1. Once cooked, transfer the chicken to a clean plate or cutting board. Tent loosely with foil and let it rest for 5-10 minutes. This crucial step allows the juices to redistribute throughout the meat, resulting in more tender and flavorful chicken.
2. After resting, if you cooked larger pieces or strips, slice or dice the chicken into bite-sized pieces suitable for stuffing into pitas.

Step 5: Prepare the Fillings & Warm the Pitas

1. Chop Vegetables: While the chicken rests, dice the tomatoes and cucumber, and thinly slice the red onion. Prepare the Kalamata olives and crumble the feta cheese if using.
2. Warm the Pitas: Warming the pitas makes them soft, pliable, and much more delicious. You can warm them in a few ways:

   • Oven: Wrap a stack of pitas in foil and warm in a 300°F (150°C) oven for 5-10 minutes.
   • Microwave: Wrap pitas in a slightly damp paper towel and microwave on high for 20-30 seconds, until warm and soft.
   • Grill/Stovetop: Briefly grill or toast each pita on a dry skillet for about 15-30 seconds per side until warm and slightly puffed.

Step 6: Assemble the Greek Chicken Stuffed Pitas

1. Lay Out Pitas: Place a warm pita bread on each plate.
2. Layer Ingredients: If using pocket pitas, carefully cut off a sliver of the top edge and gently open the pocket. If using pocketless pitas, lay them flat.
3. Add Chicken: Spoon a generous amount of the cooked Greek chicken into the pita pocket or onto one half of the flat pita.
4. Add Veggies: Top the chicken with diced tomatoes, cucumber, and thinly sliced red onion. Add Kalamata olives if desired.
5. Drizzle Tzatziki: Spoon a generous dollop (or two!) of the chilled tzatziki sauce over the chicken and vegetables.
6. Sprinkle Feta: Add a sprinkle of crumbled feta cheese for that salty, tangy kick.
7. Garnish: Garnish with fresh parsley or dill, if you like.
8. Serve: Serve immediately with extra lemon wedges on the side for squeezing over the top. Fold pocketless pitas like a taco or gyro.
