"A very delicious, mayonnaise-based cauliflower salad. Mom's been making it for over 30 years. It wows everyone who tastes it. Don't bring it to your next potluck unless you plan on bringing it every time."
1Combine cauliflower, green onions, and radishes in a large bowl. Whisk mayonnaise, sour cream, Parmesan cheese, and garlic powder in another bowl; fold mayonnaise mixture into vegetables. Refrigerate until chilled.
