Preheat oven to 425 degrees. Spray a baking sheet with non-stick spray then set aside.
In a large bowl, combine ground turkey, salsa, bread crumbs, cheddar cheese, egg, garlic, salt, and pepper. Mix until just combined.
Divide mixture into 4 equal-sized portions then form into loaves and place onto prepared baking sheet. Bake for 20-24 minutes, or until no longer pink in the center, then let rest for 5 minutes before serving.
