Preheat the oven to 375°F (190°C).
In a large skillet over medium heat, brown the ground turkey until no longer pink, breaking it up as it cooks.
Drain any excess fat from the skillet, then stir in the salsa until the meat is evenly coated; remove from heat.
In a mixing bowl, combine the cottage cheese, mozzarella, cumin, chili powder, salt, black pepper, and 1/4 cup chopped cilantro until blended.
Spread half of the meat mixture in the bottom of a 9 x 13-inch casserole dish.
Top with half of the cheese mixture, then arrange half of the tortilla strips over the cheese.
Repeat the layers with the remaining meat, cheese mixture, and tortillas, then sprinkle the shredded cheddar evenly over the top.
Cover loosely with foil and bake for 30 minutes, until heated through and cheese is melted. Remove the foil and bake 5 additional minutes to lightly brown the top.
Let the casserole rest 5–10 minutes before serving, then garnish with additional cilantro if desired.
