In a bowl, whisk together 0.5 tsp olive oil, 0.5 tbsp lemon juice, minced garlic, cumin, coriander, paprika, turmeric, cinnamon, salt, and pepper.
Slice the chicken breast into bite-sized strips and toss in the marinade until well coated.
Heat the remaining 0.5 tsp olive oil in a skillet over medium-high heat and sear the chicken for 6-8 minutes until golden and cooked through.
While chicken cooks, dice the cucumber, halve the cherry tomatoes, and finely chop the red onion and parsley.
In a small ramekin, stir together the Greek yogurt, tahini, and the remaining 0.5 tbsp lemon juice until smooth.
Assemble the bowl by placing the cooked rice at the base, topping with the spiced chicken and fresh vegetables, then finishing with a dollop of the creamy yogurt sauce.
