Slice the chicken breast into thin, bite-sized strips and place them in a mixing bowl.
Toss the chicken with the cumin, coriander, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat the olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 5-7 minutes, turning occasionally until the edges are crispy and the meat is cooked through.
While the chicken cooks, whisk together the tahini and lemon juice in a small ramekin, adding a teaspoon of water at a time until it reaches a pourable consistency.
Prepare the bowl by layering the cooked quinoa at the bottom.
Top the quinoa with the seared chicken, diced cucumber, halved cherry tomatoes, and thinly sliced red onion.
Drizzle the lemon-tahini sauce over the entire bowl and garnish with freshly chopped parsley.
