In a large skillet, heat a drizzle of cooking oil over medium heat. Add the ground turkey or beef and cook until browned, breaking it apart with a spatula. Season with salt and pepper.
Once the meat is cooked through, stir in the black beans, diced tomatoes with green chilies, corn, taco seasoning, and diced bell peppers. Let the mixture simmer for about 5 minutes to blend the flavors.
In a large mixing bowl, combine the sour cream and salsa, mixing until well combined.
In a greased baking dish, create layers: start with half of the tortilla strips at the bottom, followed by half of the meat mixture, and then half of the sour cream and salsa mix. Sprinkle half of the cheddar cheese on top.
Repeat the layering with the remaining tortilla strips, meat mixture, sour cream mixture, and finish with the remaining cheddar cheese on top.
Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes.
After 25 minutes, remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and slightly golden.
Once cooked, remove from the oven and let it cool for a few minutes. Garnish with sliced green onions before serving.
Notes
Serve directly from the baking dish or in bowls with garnishes.
