Combine the chopped broccoli and cauliflower in a large bowl.
In a separate bowl, combine the mayonnaise, sour cream, sugar, and salt to make a creamy dressing.
Add the dressing to the broccoli–cauliflower mix, stirring to evenly coat the vegetables. Stir in the bacon and the cheese, reserving a small amount to sprinkle on top of the salad just before serving.
