Preheat the oven to 400 degrees F. Line a large sheet pan with parchment paper.
Cook the rice: Place a medium pot over medium heat and add in olive oil. Once oil is warm add in onion and saute, stirring occasionally, until onions are soft and golden, 2 to 3 minutes. Stir in the garlic and turmeric and cook until fragrant, 30 seconds. Add in the rice, kosher salt and stir until rice is evenly coated, 30 seconds. Add in the water and bring the rice to a gentle boil over medium-high heat for 1 minute, then immediately cover, reduce heat to low, and cook for 15 to 18 minutes until rice is tender and all the liquid has been absorbed. Remove from heat, fluff with a fork, then replace the cover and allow rice to steam for 5 more minutes. Taste and add more salt and pepper, as needed.
While the rice cooks, shred the zucchini and prepare the meatballs: Use a box grater to shred the zucchini. Place a paper towel or clean dish towel/cheese cloth over a large bowl and squeeze ALL of the moisture out of the zucchini. Discard the liquid, then place the zucchini back in the large bowl. It should equal about ½ cup.
Form the meatballs: To the same large bowl, add the ground chicken, panko, egg, salt, paprika, garlic powder, cumin, turmeric, cinnamon and lots of freshly ground black pepper. Use clean hands to mix until well combined; avoiding overmixing, otherwise meatballs will become tough. Form into 20 golf-ball sized meatballs, placing on the prepared baking sheet, at least 1-inch apart.
Bake the meatballs: Bake until a meat thermometer inserted into the middle of the meatball reads 165 degrees F, 15 to 18 minutes.
While the meatballs bake, prepare the salad and make the sauce: In a medium bowl, add the tomatoes, cucumbers, onion, parsley, lemon juice, and salt. Stir until well-combined, then set aside at room temperature to allow the flavors to come together.
Make the sauce: In a medium bowl, whisk together the tahini, yogurt, lemon juice, water, garlic, maple syrup, and salt until well combined and smooth. Add more taste to taste, if needed.
Assemble the bowls: Add a scoop of the rice to one side of a shallow bowl, then add the 5 meatballs next to it and about 1/4th of the salad next to that. Drizzle sauce on wherever you’d like. Serve with warm pita bread for dipping and scooping, if desired.
