This is bullshit and you know it. I don't even bother with making them in low quantity, 100 is the minimum.
Using hot potatoes for the stuffing is an awful idea. So just cook your potatoes in advance. Not only that but if you "just mash it all together" you will end up with chunks.
You want to use pic related or meatgrinder to get smooth texture for white cheese and potatoes.
Chopping up onions and getting it nice and caramelized also takes 30 minutes or so. You also want to make the garnish.
You can do some things in parallel but you can't do everything at once.
Having 2 people in the kitchen will cut prep time in half for sure.
