01 - In a mixing bowl, whisk together the olive oil, lemon juice, minced garlic, dried oregano, dried thyme, paprika, salt, and black pepper. Add the chicken breasts and turn to coat evenly. Cover and refrigerate for at least 20 minutes, or up to 2 hours for deeper flavor.
02 - Heat 1 tablespoon of olive oil in a saucepan over medium heat. Add the rice and stir for 1 minute to lightly toast the grains. Pour in the water and salt, bring to a boil, then cover, reduce heat to low, and simmer for 12 to 15 minutes. Remove from heat and let rest, covered, for 5 minutes. Fluff with a fork before serving.
03 - Combine the Greek yogurt, grated and squeezed cucumber, chopped dill, minced garlic, olive oil, and lemon juice in a bowl. Season with salt and pepper to taste. Stir until well blended and refrigerate until ready to serve.
04 - Heat a grill pan or skillet over medium-high heat. Remove the chicken from the marinade and grill for 5 to 6 minutes per side, or until the internal temperature reaches 165°F and the juices run clear. Transfer to a cutting board and rest for 5 minutes before slicing into strips.
05 - Divide the fluffy rice among four bowls. Arrange the sliced grilled chicken, diced cucumber, halved cherry tomatoes, sliced red onion, Kalamata olives, and crumbled feta over the rice in each bowl. Spoon the tzatziki sauce generously on top and finish with fresh herbs and lemon wedges.
