01 - Rinse rice under cold water until it runs clear. In a saucepan, bring 2 cups of water to a rolling boil. Add the rice, lemon zest, and salt. Cover with a tight-fitting lid, reduce heat to low, and simmer for 12-15 minutes until all liquid is absorbed. Remove from heat, fluff gently with a fork, and set aside covered to keep warm.
02 - Pat the shrimp dry with paper towels. In a mixing bowl, combine the shrimp with olive oil, minced garlic, dried oregano, smoked paprika, sea salt, black pepper, and fresh lemon juice. Toss to coat evenly and let the shrimp marinate at room temperature for 10 minutes.
03 - Heat a large skillet over medium-high heat until it begins to lightly smoke. Add the marinated shrimp in a single layer, working in batches if needed to avoid crowding. Sear for 2-3 minutes per side until the shrimp turn pink, curl slightly, and are fully opaque throughout. Transfer to a plate and tent loosely with foil.
04 - While the shrimp cooks, combine the Greek yogurt, grated and well-drained cucumber, minced garlic, fresh dill, lemon juice, and olive oil in a bowl. Season with salt and pepper to taste, stir until smooth, and refrigerate until ready to serve to allow the flavors to meld.
05 - Divide the warm lemon rice and fresh greens evenly among four bowls. Arrange the seared shrimp, halved cherry tomatoes, diced cucumber, sliced Kalamata olives, and thinly sliced red onion over each portion. Crumble feta cheese generously over each bowl, drizzle with tzatziki sauce, and finish with a sprinkle of fresh chopped parsley. Serve immediately with lemon wedges on the side.
