Combine all ingredients in a bowl or small food processor and blend.
Refrigerate for 2+ hours before eating.
For salad assembly, prepare iceberg wedges, crispy bacon, tomatoes, an herb such as chives (my vote) or parsley, and a few extra blue cheese crumbles on top because itâ€™s yummier that way. Avocado is also a nice touch if you have one.
1. Letting the dressing sit in the fridge for at least two hours, or overnight if possible, allows the blue cheese to diffuse into the dressing. 2. A slightly thinner dressing vs an ultra thick and heavy dressing will get down into the layers of iceberg more easily. These are the things that matter. 3. Don't go too heavy on the salt. Blue cheese has a salty bite to it, so it won't need much. But freshly cracked black pepper is a win, so crack away!
