Cook ground beef and ground turkey in a large skillet (or cast iron). Sprinkle Cajun seasoning while the meat is browning.
Add the chopped onion, cooking until it becomes translucent. Drain off the grease.
Stir in the rice and cabbage, tomato sauce, water, Rotel and it’s juices.
Bring the skillet to a boil then reduce the heat to medium low.
Cover the skillet allowing it to simmer for 20 minutes. (Check the rice and cabbage, at the 20 minute mark, to make sure that both the rice and cabbage are cooked.)
Top with shredded sharp Cheddar cheese.
Replace the lid and allow time for the cheese to melt.
Remove from heat and allow to cool a few minutes before serving.
