Slice the chicken breast into thin, bite-sized strips and place them in a small mixing bowl.
Toss the chicken with the ground cumin, smoked paprika, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat the avocado oil in a medium skillet over medium-high heat until shimmering.
Add the seasoned 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, chop the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small ramekin, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until it reaches a smooth, drizzling consistency.
Assemble the bowl by placing the fluffy cooked quinoa at the base, followed by the fresh vegetables.
Top the bowl with the warm crispy chicken and finish with a generous drizzle of the creamy lemon-tahini sauce.
