Add white rice and water to a pot. Bring to a boil, then reduce to low heat, cover, and simmer for 12-15 minutes, or until the water is fully absorbed. Remove from heat and let sit covered for 5 minutes, then fluff with a fork. Set aside.

Meanwhile, heat the oil in a skillet over medium heat and add the ground turkey. Cook for 6-8 minutes, breaking it apart with a spoon. When the turkey is almost fully browned, stir in the frozen spinach and cook for 3-4 minutes, until the spinach is warmed through and the turkey is fully cooked. Season with salt and pepper. Turn off the heat.

Serve the cooked rice topped with the turkey mixture, Greek yogurt, cheddar cheese, and a drizzle of sriracha.
