Cook bacon according to package. Allow to cool and then crumble.

Chop broccoli and cauliflower into small florets.

Mix dressing ingredients well and combine with broccoli, cauliflower and onions. (I like to let my salad sit for a few hours and mix it every hour or so so the broccoli florets absorb some of the dressing.) If you like crunchier broccoli salads, don't let it sit.

Before serving, add bacon and cheese and mix again.
