Slice the chicken breast into thin, bite-sized strips and place them in a small mixing bowl.
Toss the chicken with olive oil, cumin, paprika, turmeric, sea salt, and black pepper until evenly coated.
Heat a non-stick skillet over medium-high heat and cook the chicken until golden brown and cooked through, approximately 6 to 8 minutes.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small ramekin, whisk together the tahini and lemon juice with a teaspoon of warm water until the sauce reaches a smooth, pourable consistency.
Place the pre-cooked warm brown rice in the center of a bowl.
Arrange the spiced chicken, cucumber, tomatoes, and red onion over the rice.
Drizzle the creamy tahini sauce over the entire bowl and garnish with freshly chopped parsley.
