Cook the macaroni pasta according to the package instructions until al dente.
Drain the pasta and set aside.
In a blender or food processor, combine cottage cheese, light cream cheese, Greek yogurt, shredded cheddar cheese, Parmesan cheese, Dijon mustard, garlic powder, salt, and pepper.
Blend until smooth and well combined.
In a large mixing bowl, combine the cooked macaroni pasta with the blended cheese mixture.
Gently toss until the pasta is evenly coated with the cheese sauce.
If the pasta needs thinned add milk or half and half until reaching your desired consistency.
If you prefer a baked version, transfer the mixture to a baking dish.
Bake in a preheated oven at 350°F (175°C) for about 15-20 minutes or until the top is golden and bubbly.
