Marinate the Chicken: Whisk together olive oil, lemon juice, honey, garlic powder, oregano, basil, salt, pepper, and red pepper flakes. Pound the chicken breasts to ensure uniform thickness, then marinate for at least 30 minutes.
Prepare Tzatziki Sauce: Mix Greek yogurt, grated cucumber, lemon juice, olive oil, minced garlic, salt, and fresh dill until smooth and well-blended.
Cook Rice or Quinoa: Follow package instructions to cook rice or quinoa while the chicken marinates.
Grill the Chicken: Preheat air fryer to 380°F. Cook marinated chicken for about 10 minutes or until it reaches an internal temperature of 165°F.
Chop Veggies and Assemble Bowls: Chop grape tomatoes, cucumbers, red onions, and shred romaine lettuce. Slice the cooked chicken.
Build Your Greek Chicken Bowl: Start with a scoop of rice or quinoa, layer with veggies and sliced chicken, and top with tzatziki sauce and crumbled feta.
