Cut potatoes into medium to large chunks, chop onion and add to potatoes. Cover with water and bring to a boil, then turn heat down to simmer. While potatoes are cooking  - about 15- 20 minutes- prepare the gravy mix( I prefer Southeastern Mills) per directions. Break potatoes up with a large spoon( I like it chunky) and add prepared gravy mix, add parsley flakes, let cool and enjoy! will keep in fridge for several days. I have not tried freezing, but it might be ok.
