Slice the chicken breast into thin, bite-sized strips.
In a medium bowl, toss the chicken with olive oil, cumin, smoked paprika, turmeric, garlic powder, sea salt, and black pepper until evenly coated.
Heat a non-stick skillet over medium-high heat and cook the chicken for 6 to 8 minutes, stirring occasionally, until golden brown and fully cooked.
While the chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion to create a fresh salad.
In a small ramekin, whisk together the tahini and lemon juice, adding a teaspoon of water at a time until it reaches a smooth, drizzling consistency.
Place the warm cooked basmati rice in a bowl, top with the spiced chicken and the vegetable salad, and finish with a drizzle of the tahini sauce.
