Cook the basmati rice according to package instructions using water or gluten-free broth.
In a bowl, toss the sliced chicken breast with cumin, coriander, smoked paprika, turmeric, sea salt, black pepper, and minced garlic.
Heat olive oil in a skillet over medium-high heat and sear the chicken until cooked through and slightly charred.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
In a small jar, whisk together the tahini and lemon juice with a splash of warm water until smooth and pourable.
Assemble the bowl by layering the rice, spiced chicken, and fresh vegetables, then finish with the creamy tahini drizzle.
