Slice the chicken breast into thin, bite-sized strips.
In a small bowl, whisk together the garlic powder, ground cumin, smoked paprika, sea salt, and black pepper.
Toss the chicken strips in the spice blend until evenly coated.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sear for 3-4 minutes per side until golden brown and cooked through.
While the chicken cooks, prepare the dressing by whisking together the tahini and lemon juice with a splash of warm water to reach a drizzling consistency.
Assemble the bowl by placing the baby spinach and cooked quinoa at the base.
Top with the diced cucumber, halved cherry tomatoes, and the crispy shawarma chicken.
Garnish with freshly chopped parsley and drizzle the lemon-tahini sauce over the top before serving.
