In a small bowl, whisk together 0.5 tbsp olive oil, lemon juice, minced garlic, cumin, paprika, turmeric, salt, and pepper.
Slice the chicken breast into bite-sized pieces and toss in the marinade until every piece is well coated.
Heat a large skillet over medium-high heat with the remaining 0.5 tbsp olive oil.
Add the chicken to the skillet and sauté for 6 to 8 minutes until golden brown and cooked through.
Remove the chicken from the pan and add the cauliflower rice, sautéing for 3 to 4 minutes until tender and lightly toasted.
Assemble the bowl by layering the cauliflower rice, seasoned chicken, diced cucumber, halved cherry tomatoes, and sliced red onion.
Drizzle the entire bowl with tahini and garnish with chopped fresh parsley before serving.
