This salad is so good there is never any left and I am always asked for the recipe. I used to make this when I worked in a deli many years ago- when things were all homemade - not from a box or a can or a jar. If making this for a picnic- you better double it!!
Place cauliflower pieces, crumbled bacon, cheese and onions in a large bowl. Mix together in another bowl the remaining ingredients. Blend well. Add just enough of the sauce over the cauliflower mixture to moisten slightly- do not over whelm it with the sauce- serve any extra on the side , if desired. Keep chilled until ready to serve. This is to die for!!!
