In a medium bowl, combine the sliced chicken with olive oil, minced garlic, dried oregano, smoked paprika, sea salt, and pepper. Mix well to ensure the chicken is evenly coated with the marinade. Cover the bowl and refrigerate for at least 30 minutes.
In a medium saucepan, bring the vegetable broth to a boil over medium-high heat. Once boiling, stir in the rinsed quinoa. Lower the heat to a gentle simmer, cover, and let it cook for about 15 minutes, or until all the liquid is absorbed. Fluff the quinoa with a fork and allow it to sit aside, uncovered.
In a large skillet over medium-high heat, add the marinated chicken strips. Cook them for 6-8 minutes, stirring occasionally, until the chicken is thoroughly cooked and exhibits a delightful golden brown color.
While the chicken is cooking, chop the cherry tomatoes in half, dice the cucumber, and thinly slice the red onion. Set these fresh toppings aside.
In individual serving bowls, layer a generous portion of quinoa as the base. Add the sautéed chicken strips on top, followed by the vibrant diced cucumber, halved cherry tomatoes, sliced red onion, crumbled feta cheese, and a sprinkle of fresh parsley.
Drizzle freshly squeezed lemon juice over each bowl, followed by a generous swirl of tzatziki sauce for added creaminess. Sprinkle lemon zest atop the bowls for a refreshing burst of citrus flavor.
Notes
For an eye-catching presentation, consider using clear glass bowls to showcase the colorful layers of the ingredients. Garnish with additional parsley and lemon wedges on the side for an inviting touch.
