In a high speed blender, add cottage cheese, milk, garlic, Dijon mustard and vinegar. Process until smooth and set aside.
In a small skillet, add nuts and toast on low-medium heat until fragrant and golden, stirring often. Transfer to a cutting board, let cool a bit and chop coarsely.
In a medium bowl, add toasted pecans, chicken, celery, onion, parsley, salt and pepper. Pour dressing on top and stir to combine. Mix and adjust salt to taste, if necessary.
Refrigerate for 1 hour as salad tastes best cold. Adjust any seasonings to taste, if you wish. Enjoy cold!
Notes
Store: Refrigerate in an airtight container for up to 5 days. I have not tried freezing the salad and am not sure fresh veggies and herbs will hold up well to it.
