In a large skillet over medium high-heat, cook the ground turkey for 5 to 7 minutes, or until no longer pink, stirring occasionally.
Add the beans, corn, salsa, and water, stirring well to mix. Bring to a boil.
Add the rice, stirring well to mix. Return to a boil; reduce heat to low; cover and simmer for 5 minutes.
Remove from heat, and let stand for 5 minutes, covered, until water is absorbed and rice is tender.
Transfer to a serving dish. Sprinkle with cilantro and cheese. Serve with diced avocado, if desired and tortillas.
