@CalamityJane,
Great question CalamityJane
I do use store bought dressings, for now.
But, I add things to my salad that are fermented and contain vitamin K like pickled olives, pickled mushrooms, pickled fetta cheese etc.
I often use some of the spice laden brine from them so I require much less dressing.
I have surmised that eventually I will get bored with the store bought dressing selection but they do have a lot of variety, many of which I have not tried yet.
I have a small herb garden where I grow mint, chives, parsley and oregano. I add these fresh to my salads as well.
I use the store bought dressings sparingly as possible.
The weight is dropping off so it is working and I don't think I will reach a plateau with this diet. I am not starving myself and the nutrition level is through the roof.
I can make my own dressings, peanut butter and rice vinegar with honey is a good one.
