In a small bowl, combine the ground cumin, garlic powder, turmeric, sea salt, and black pepper.
Coat the chicken breast evenly with the spice mixture on both sides.
Heat the olive oil in a medium skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-6 minutes per side, or until the exterior is golden-brown and the internal temperature reaches 165°F.
While the chicken cooks, whisk together the tahini and lemon juice in a small ramekin, adding a teaspoon of water at a time until a pourable consistency is reached.
Slice the cooked chicken into thin strips.
Assemble the bowl by placing the cooked quinoa at the base and topping it with the sliced chicken, diced cucumber, and cherry tomatoes.
Drizzle the tahini sauce over the bowl and garnish with freshly chopped parsley before serving.
