Combine the rinsed rice, 2 cups water and 1/2 tsp salt in a medium saucepan. Bring to a boil, cover, reduce heat to low and simmer 15 minutes. Remove from heat and let stand 5 minutes, then fluff with a fork.
Meanwhile, heat a large nonstick skillet over medium-high heat. Add the turkey and cook 6 to 8 minutes, breaking it up, until no longer pink. Stir in the taco seasoning with 2 tbsp water and simmer 1 minute.
Stir the black beans and corn into the skillet and cook 2 to 3 minutes, until warmed through.
In a small bowl, stir the Greek yogurt with the lime juice and a pinch of salt.
Divide the rice among 4 containers, then top with the turkey mixture and cherry tomatoes.
Serve with salsa, cilantro and the lime yogurt. Store covered in the refrigerator up to 4 days; add the lime yogurt and salsa just before eating.
