Begin to cook the turkey over medium heat, breaking it up into pieces as it cooks.
Add the prepared taco seasoning, then continue to stir and cook for 1-2 minutes more.
Drain the black beans then add them to the skillet with the diced tomatoes (with juices) and frozen corn (no need to thaw). Stir the ingredients in the skillet to combine, then heat through over medium.
While the mixture is heating, slice the green onions. Stir the green onions into the skillet just before serving.
