Place the cream cheese, mayonnaise, sour cream, sun-dried tomatoes, salt, black pepper and hot sauce in the bowl of a food processor. Puree until smooth, about 20 seconds, stopping once to scrape down the sides of the bowl.
Add the green onions and pulse twice to evenly distribute them. Serve with your favorite crackers, carrots or pretzels. The dip can be stored in an airtight container in the refrigerator for up to 4 days. Remove and let sit at room temperature for 30 minutes before serving.
