Slice the chicken breast into thin, bite-sized strips for even cooking.
In a medium bowl, toss the chicken with sea salt, black pepper, cumin, coriander, turmeric, and garlic powder until well coated.
Heat the extra virgin olive oil in a large skillet over medium-high heat.
Add the chicken to the skillet and sauté for 6 to 8 minutes until the edges are golden brown and the meat is cooked through.
While the chicken cooks, dice the cucumber, tomato, and red onion into small pieces.
In a small ramekin, whisk together the tahini and lemon juice, adding a teaspoon of warm water at a time until it reaches a pourable consistency.
Assemble the bowl by placing the warm basmati rice at the base, followed by the spiced chicken and the fresh vegetable medley.
Drizzle the creamy tahini sauce over the entire bowl before serving.
