In a double boiler, liquify the cottage cheese, stirring frequently. With some brands, this may not happen completely. You'll still have small chunks of cottage cheese left. But that's okay. You'll be blending it anyway.
Put the warm cottage cheese and the rest of the sauce ingredients in a blender and blend until smooth. If you feel the sauce is too thick, feel free to add a splash or two of milk until you reach your desired constancy.
In a large mixing bowl, combine your pasta, chicken and any toppings you'd like to add. Mix well.
Put your pasta mix on a plate and pour some sauce over the top to serve. Serve quickly as the sauce cools off fast.
NOTE: If using avocados, you may want to top the sauce with the avocado as mixing it in can make it rather mushy.
