Slice the chicken breast into thin strips and place them in a bowl.
In a small ramekin, combine the cumin, smoked paprika, turmeric, garlic powder, sea salt, and black pepper.
Toss the chicken with the spice blend and half of the lemon juice until evenly coated.
Heat the olive oil in a non-stick skillet over medium-high heat and sauté the chicken for 6-8 minutes until golden brown and cooked through.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and thinly slice the red onion.
In a small bowl, whisk the tahini with the remaining lemon juice and 1 teaspoon of warm water until smooth and pourable.
Place the warm cooked brown rice in the base of a bowl and top with the spiced chicken and the fresh vegetable salad.
Garnish with chopped fresh parsley and drizzle the creamy tahini sauce over the entire bowl before serving.
