I concocted this 3 years ago and really liked it. I don't know why I didn't make it again until recently, but it was still good.
More or less, this is the recipe I used for the dressing:
Creamy Lemon Dressing from allrecipes.com.
1/3 c fresh lemon juice
4 t. lemon zest
3 cloves garlic minced
2 t. dijon mustard
1/4 t. salt
1/4 t pepper
1/2 c olive oil
1/2 c sour cream
Plus shrimp, pasta, celery, asparagus and broccoli (lightly cooked and cooled in an ice-water bath), served on a bed of spinach or arugula.
It's so nice when your vision matches reality.
