Add all ingredients for the creamy queso dressing to a food processor and pulse, scraping down the sides of the food processor as needed, until smooth.
In a large bowl, toss together the romaine, cabbage, onion, corn, beans, radish, avocado, and cilantro. Drizzle with desired amount of creamy queso fresco dressing and toss again.
Transfer to serving plates and top with pepitas and extra queso fresco, if desired.
