This a great salad to have for a simple lunch or to serve with a nice dinner. Fresh ingredients make this salad very elegant and the wedge presentation makes it a great starter for a special occasion dinner. It is best to chill the dressing for 24 hours prior to serving.
Combine 1/2 pound blue cheese, sour cream, buttermilk, mayonnaise, vinegar, olive oil, sugar, garlic, and pepper in a bowl; blend using a hand mixer; chill until serving.
Build the salad by placing 1 lettuce wedge on each of 8 plates. Drizzle equal amounts of dressing over each wedge. Scatter tomatoes, onion, and 1/2 pound blue cheese over each salad.
