Here is a recipe for a really delicious blue cheese dressing. No additives, no sugar, and you can make it in just a few minutes.
A few thinly slices red onion
½ cup sour cream or plain Greek yogurt
½ cup mayonnaise
1 T fresh squeezed lemon juice or white wine vinegar
3 T buttermilk
Sea salt and freshly ground black pepper
Evenly divide red onion and celery on top of each lettuce.
Whisk together the sour cream or yogurt and mayonnaise in a medium bowl.
Add most of the crumbled blue cheese. Mash and mix with a fork until fairly smooth, but not completely smooth.
Stir in the lemon juice and as much buttermilk as needed.
Season to taste with salt and pepper.
Spoon some dressing on top of each wedge, add the rest of the crumbled blue cheese.
