Place cauliflower in a food processor and pulse until small pieces of "rice."
In a large skillet, cook sausages. Remove sausages, reserving drippings. When cool enough to handle, cut sausages in half lengthwise, then into 1/4-in. pieces; set aside.
Saute onion, garlic, cauliflower "rice" and peppers in drippings until tender, about 4 minutes.
Add the next eight ingredients and salt; cook and stir for 5 minutes.
Stir in ham, shrimp, parsley and sausage; mix lightly. Enjoy!
