For a while, this was the most searched-for recipe on this site. I recently read a copy of the South Beach Diet, and I realized then that this is similar to Agatson’s “Surprise South Beach Mashed ‘Potatoes.’” That’s his low glycemic index substitute for mashed potatoes.

1 large head cauliflower
1/2 C grated parmesan cheese
1/2 C sour cream
1 - 2 T mayonnaise
Bacon bits or chives (optional)

Remove leaves and break cauliflower into chunks, chop the core in 1/2-inch pieces. Steam until tender and transfer to a large bowl. While it’s hot, use a potato masher to mash into small chunks, then toss with a little salt and the parmesan cheese. Add the sour cream and mayo and mix thoroughly. Finished dish should be thick and chunky-smooth.

Fold in either bacon bits or chives, or just sprinkle them on top.

South Beach Diet version:
4 C cauliflower
1 oz artificial butter spray
1 oz fat-free half-and-half
Salt and pepper
Instead of a potato masher, he recommends a food processor.
