I saw this recently, and plan to make it this week with some leftover cauliflower.
1 head of cauliflower cut into florets
1 egg
panko breadcrumbs (don't remember the amount, I would wing it anyway)
1/2 cup shredded cheddar cheese (I'd use some reggiano instead)
Olive Oil
Boil cauliflower until tender, drain, and mash well with a potato masher
Beat egg well, add mashed cauliflower, breadcrumbs and cheese.
Sautee lightly in oil until browned, keep in warm oven until rest are ready. Serve immediately.
Sounds yummy, no?
