Preheat oven to 375°F (190°C) and lightly coat a 9x13 inch baking dish with non-stick spray.
Cook chickpea pasta in boiling water for 2 minutes less than the package instructions to ensure it remains firm during baking; drain and set aside.
In a blender or food processor, combine cottage cheese, Parmesan cheese, skim milk, minced garlic, Italian seasoning, salt, and pepper. Process until the texture is completely smooth.
In a large mixing bowl, combine the par-cooked pasta, cubed chicken, and the blended sauce. Mix thoroughly until all components are evenly coated.
Transfer the mixture into the prepared baking dish and spread in an even layer.
Sprinkle the shredded mozzarella cheese uniformly over the top.
Bake for 20 to 25 minutes, or until the cheese is melted and slightly golden and the sauce is bubbling.
Remove from oven and garnish with fresh parsley before serving.
