Preheat your oven to 350°F (175°C).

In a skillet over medium heat, brown the ground beef or turkey until fully cooked. Break it up with a spoon as it cooks.

In a large mixing bowl, combine the cooked meat, black beans, corn, and half of the salsa. Stir until mixed well.

In a baking dish, spread a thin layer of the remaining salsa on the bottom. Add half of the crushed tortilla chips, then the meat mixture, and top with the rest of the tortilla chips.

Place the casserole in the preheated oven and bake uncovered for 20-25 minutes or until heated through and the chips are golden.

Remove from the oven and let it sit for 5 minutes before serving with your favorite toppings.
