Slice the chicken breast into thin strips and place in a small bowl.
Mince the garlic and combine it with the cumin, coriander, turmeric, paprika, sea salt, and black pepper. Toss the chicken with the spice blend until evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat. Add the chicken strips in a single layer and cook for 3-4 minutes per side until golden brown and crispy.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and thinly slice the red onion.
In a small ramekin, whisk together the tahini, lemon juice, and water until a smooth, pourable dressing forms.
Place the cooked quinoa in the center of a bowl and top with the crispy chicken strips.
Arrange the cucumber, tomatoes, and red onion around the chicken.
Drizzle the lemon-tahini sauce over the entire bowl and serve immediately.
