- Thinly slice peppers and onions. Heat olive oil in a large, heavy skillet over medium heat. Add peppers and onions and saute until slightly softened, about 5-6 minutes.
- Add minced garlic and saute for 1 minute. Add tomatoes, cajun seasoning, crushed red pepper, and sausages. Cover and reduce heat and cook for about 10 more minutes, stirring occasionally, until peppers and onions are cooked to desired doneness.
- Bring a large pot of water to a boil. Add 1 tsp of salt, cauliflower florets, and garlic cloves. Cool until tender, about 10-12 minutes. Drain.
- Place cauliflower and garlic into a food processor. Add remaining ingredients and puree until very smooth, scrapping down the sides as needed. Season with salt and pepper to taste.
