It's the best I've had so far.

1 head of cauliflower, washed and chopped up into 1/2 in. or
smaller pieces
4 slices of crisp, cooked bacon, chopped fine
1 bunch of green onions chopped fine equaling 1/4 to 1/2 cup as
desired or use vadalia onion if in season
3/4 cup shredded parmesan cheese, freshly grated or from the
bag (not from the can)

Mix all this in a big bowl.

Then in a small bowl, mix until well blended, the following-

1 cup of mayonnaise
3/4 cup sour cream
1/2 tsp. worchestershire sauce
dash or more of hot sauce
1/2 tsp. salt
sugar substitute to equal 1 tbsp. sugar
1 tbsp. cider or basalmic vinegar

Pour the dressing over the vegetables and mix well, serve or chill until later.
