Rice cauliflower in a food processor until coarsely chopped, slightly larger than typical cauliflower rice. Using store bought riced cauliflower will work also.
Add cauliflower to a large microwavable bowl or dish. Microwave for 4 minutes. Alternately, add to a steamer and steam for about 7 minutes on the stovetop.
Add cooked riced cauliflower to a large thin dish towel, and twist to squeeze the excess water out of the cauliflower. Try to squeeze out about 3/4 of a cup of water.
Add the cauliflower, almond flour, parsley, egg, salt and pepper to a bowl, and mix well to combine.
Add 1/2 tablespoon of avocado oil to a skillet over medium heat. Add sausage patties, and 2 large mounds of the cauliflower mixture.
Use a spatula to press down the cauliflower into round patties.
Cover the skillet and allow to cook until golden brown, about 5-7 minutes.
Carefully flip the cauliflower patties and sausages, and continue to cook uncovered for 4-5 minutes.
Repeat until all the cauliflower mixture and sausages are cooked.
Drizzle with avocado sauce and chopped tomatoes, if desired.
