Slice the chicken breast into thin strips and toss in a bowl with the cumin, smoked paprika, turmeric, sea salt, black pepper, and half of the olive oil.
Heat a large skillet over medium-high heat and sear the chicken strips for 3-4 minutes per side until they are golden brown and cooked through.
Remove the chicken from the skillet and set aside; in the same pan, add the remaining olive oil and sauté the cauliflower rice for 5 minutes until tender and slightly toasted.
While the cauliflower rice cooks, whisk the tahini and lemon juice together in a small bowl, adding a teaspoon of warm water at a time until it reaches a smooth, drizzling consistency.
Dice the cucumber and halve the cherry tomatoes to prepare the fresh vegetable topping.
Assemble the bowl by placing the cauliflower rice at the base, topping with the spiced chicken and fresh vegetables, then finishing with a drizzle of the tahini sauce and a sprinkle of chopped parsley.
