Slice the chicken breast into thin, even strips and place them in a small mixing bowl.
Add the olive oil, lemon juice, minced garlic, cumin, coriander, turmeric, sea salt, and black pepper to the chicken and toss until thoroughly coated.
Heat a non-stick skillet over medium-high heat and sauté the chicken strips for 6 to 8 minutes until golden brown and fully cooked through.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely chop the red onion to prepare the fresh salad.
In a small ramekin, whisk the tahini with water until it reaches a smooth, pourable consistency.
Assemble the bowl by placing the warm cooked brown rice at the bottom, then top with the spiced chicken and the fresh vegetable salad.
Finish the dish by drizzling the creamy tahini sauce over the top and serve immediately.
