Preheat the oven to 375°F (190°C).
In a medium skillet over medium heat, cook the ground turkey until no pink remains, breaking it up as it cooks; drain any excess fat.
Stir the salsa into the cooked turkey until evenly combined; set the meat mixture aside.
In a medium bowl, mix the cottage cheese, shredded mozzarella, cumin, chili powder, salt, black pepper, and chopped cilantro until well combined.
Spread one-third of the turkey-salsa mixture in the bottom of a 9 x 13-inch casserole dish.
Top with one-third of the cottage cheese and mozzarella mixture, then a layer of tortilla strips to cover the cheese.
Repeat the layers with the remaining turkey mixture, cheese mixture, and tortilla strips so you have two layers total.
Sprinkle the shredded reduced-fat cheddar evenly over the top.
Cover loosely with foil and bake for 30 minutes, then remove the foil and bake an additional 5 minutes, until the casserole is heated through and cheese is melted and lightly bubbly.
Let the lasagna rest 5–10 minutes, garnish with additional chopped cilantro, then cut and serve.
