Grate the head of cauliflower with a box grater or finely chop it in a food processor. You should have about 3½ cups. Place the cauliflower in the center of a clean kitchen towel and twist it to squeeze all the water out. (This can be done in two batches to make it easier to drain all the water from the cauliflower.)

Place the cauliflower in a large bowl and add the bacon, onions, peppers, egg, flour, Cheddar cheese, paprika, salt and pepper. Mix until well combined. Shape the mixture into 8 oval shaped patties and freeze for at least 1 hour.
