In a mixing bowl, combine olive oil, lemon juice, minced garlic, oregano, paprika, salt, and pepper. Add the chicken cubes and marinate for at least 30 minutes.
While the chicken is marinating, rinse the quinoa under cold water. In a pot, combine quinoa and water or chicken broth. Bring to a boil, then reduce heat to low, cover, and simmer for about 15 minutes or until quinoa is fluffy and liquid is absorbed.
Preheat your grill or a grill pan over medium-high heat. Skewer the marinated chicken cubes onto soaked wooden or metal skewers.
Grill the skewers for about 5-7 minutes on each side, or until the chicken is cooked through and has nice grill marks. Remove from heat and let rest.
To assemble the bowls, start with a base of quinoa. Top with grilled chicken skewers, cherry tomatoes, cucumber, red onion, olives, and a generous sprinkle of feta cheese.
Drizzle with tzatziki sauce and garnish with freshly chopped parsley for added freshness.
Notes
Serve the bowls in a colorful bowl, arranging each ingredient in sections to create a vibrant display. Add a lemon wedge on the side for a pop of color and extra flavor.
