Rinse the quinoa thoroughly and cook in water according to package directions until all liquid is absorbed and grains are fluffy.
Slice the chicken breast into thin, bite-sized strips and place them in a bowl.
Toss the chicken with the cumin, paprika, dried oregano, sea salt, and black pepper until evenly coated.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken strips until golden-brown and cooked through.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small mixing bowl, whisk together the Greek yogurt, tahini, minced garlic, and lemon juice to create a smooth sauce.
Assemble the bowl by placing the cooked quinoa at the base and topping it with the crispy chicken and the fresh vegetable mix.
Drizzle the yogurt-tahini sauce over the top and garnish with freshly chopped parsley.
