Preheat oven to 375°. Heat a large skillet over medium heat.
Add ground turkey and cook, breaking it up, until almost fully cooked (about 6–8 minutes).
Sprinkle in taco seasoning and pour in the corn and black beans. Stir well and simmer for 2–3 minutes until thickened. Remove from heat.
Warm tortillas briefly so they’re flexible. Add a pinch of cheese to the tortilla, then 2-3 scoops of the turkey mixture into each tortilla.
Top with an additional layer of cheese, and gently fold, pressing down to keep the tortilla from opening up.
Arrange tacos on the baking sheet. Cover loosely with foil and bake for 10 minutes.
Remove foil and bake an additional 5-6 minutes, until cheese is melted and tortillas are heated through.
Notes
Drain the liquid from the black beans and the corn as much as possible to alleviate the ground turkey mixture from becoming too thin.Ground turkey dries out fast, especially since it’s lean. Cook it just until it’s barely done on the stove as it will bake and cook more when it goes into the oven That way it stays juicy instead of dry.Add a first layer of cheese on the tortilla before the turkey filling. This creates a melty barrier between the tortilla and the filling, which helps prevent soggy bottoms. Plus, that bottom layer of cheese gets perfectly gooey and slightly crispy at the edges.Remember to press the other half of the tortilla down on the filled side so that it does not puff up and open as it bakes.
