Preheat your oven to 375 degrees.
In a blender, combine cottage cheese, pesto, garlic powder, spinach, and water. Blend until smooth.
In a large greased 9×13-inch baking dish, add the uncooked pasta.
Pour the blended cottage cheese mixture over the pasta and stir until evenly coated.
Sprinkle one cup of mozzarella cheese over the top.
Cover the baking dish tightly with aluminum foil. Bake for 30 minutes to allow the pasta to cook through.
Remove the foil and sprinkle the remaining one cup of mozzarella cheese evenly over the dish.
Bake, uncovered, for an additional 5-10 minutes, or until the cheese is melted and bubbly.
