Add the olive oil, tamari, cumin, chilli flakes, garlic powder, parsley, minced garlic, lime juice, salt, and pepper to a bowl and mix well.
Add the chicken thighs and toss until well coated.
Cover and marinate for at least 1 hour.
Meanwhile, add the mayonnaise, Greek yoghurt, garlic, parsley, green onions, jalapeño, lime juice, olive oil, salt, and pepper to a blender or food processor.
Blend until smooth and creamy, or until you reach your preferred consistency.
Taste and adjust the salt, pepper, lime juice, or olive oil as needed.
Grill the chicken over medium-high heat until cooked through and lightly charred on the outside.
Let the chicken rest for a few minutes, then slice or chop into bite-sized pieces.
Add rice to each bowl and top with black beans, corn, tomato, red onion and grilled chicken. Drizzle generously with the parsley green sauce and serve with extra lime wedges if desired. Enjoy!
