In a separate bowl, mix the mayonnaise, sour cream, vinegar and salt and pepper. Mix until well combined, then pour over the broccoli and cauliflower. Toss until the veggies are well coated.
Cook and crumble the bacon. Then sprinkle the grated cheese, chopped green onion and crumbled bacon over the broccoli and cauliflower salad. Gently toss, then serve.
