Step 1

In a blender or a food processor combine crumbled blue cheese, yogurt, white wine vinegar, sliced green onions, water and olive oil. Blend until smooth. If the dressing is too thick, add an additional tablespoon or two of water. Salt to taste if necessary. Alternatively you can make the dressing in a bowl using a fork to mash the blue cheese and combine it with the rest of the ingredients.

Step 2

Cook the bacon and place it on a paper towel -lined plate to absorb the excess fat. Then chop it up.

Step 3

Slice the apple thinly on a mandoline or using a sharp knife.

Step 4

In a large bowl combine the salad greens, apple slices, bacon and chopped walnuts. Drizzle with half of the blue cheese dressing and toss gently to coat. Serve immediately sprinkled with additional crumbled blue cheese. Reserve the remaining salad dressing for another use.
