Preheat the oven to 375°F (190°C).
In a medium skillet over medium heat, cook the ground turkey, breaking it up, until no pink remains, about 6–8 minutes.
Drain any excess fat from the skillet, then stir the salsa into the cooked turkey until combined; remove from heat.
In a medium bowl, combine the cottage cheese, mozzarella, cumin, chili powder, salt, black pepper, and 1/4 cup chopped cilantro; mix until uniform.
Spread half of the meat mixture in the bottom of a 9 x 13-inch casserole dish.
Spoon half of the cheese mixture over the meat, then layer half of the tortilla strips to cover the surface.
Repeat with the remaining meat, cheese mixture, and tortilla strips, finishing with the remaining shredded cheddar on top.
Cover loosely with foil and bake for 30 minutes, until the casserole is heated through and the cheese is melted.
Remove the foil and bake an additional 5 minutes to lightly brown the top, then let the casserole rest 5–10 minutes before serving.
Garnish with additional chopped cilantro and serve.
