Begin by making your marinade: whisk together oil, lemon juice, spices, and garlic in a medium size bowl. Pour marinade into a large container with the chicken, and mix until chicken is well coated. Marinade for at least 1 hour, up to 24 hours.
When ready to grill, place chicken on prepared grill and cook for 4-5 minutes. Flip the chicken over, basting with any extra marinade, cooking until chicken is no longer pink (about another 5 minutes). Remove and cover with foil until ready to eat.
Make the tahini dressing: In a food processor or blender, blend your dressing ingredients: lemon juice, vinegar, tahini, coconut aminos, oil, garlic, cumin, and water. If dressing is too thick, add in additional water.
Prepare your bowls: Chop the cauliflower into florets and place inside a blender or food processor. Pulse until cauliflower forms a rice-like texture, careful not to over pulse. In a separate bowl, mix together tomatoes, cucumber, onion, and mint. Top with a pinch of salt and pepper.
Layer the bowls by adding in romaine lettuce, cauliflower rice, and then chicken. Now top with the tomato mixture, and finally drizzle with tahini dressing.
Notes
*You can also use pre made cauliflower rice, about 3-4 cups.
