Greek Yogurt Thousand Island/Russian Dressing-Updated

I love creamy dressings, but mayo packs a mean punch of calories. I'm constantly looking through the salad dressings when I pick up my weekly pound of spinach, for something new and low calorie that isn't a vinaigrette (too sour for me usually).  This week, I noticed Wegmans now caries a greek yogurt thousand island, and I was like DOH!  I can do that!  Why didn't I ever think of it?  And I bet I can yield more with less calories.

You Need:
1/2 Tbsp Simply Heinz Ketchup (any Ketchup will work-you can use whatever you like, but you'll need to adjust your calories)
1 1/2 Tbsp. Plain Greek Yogurt, Fat Free
1/2 Tbsp sweet pickle relish

If you like yours a little less relishy, adjust yogurt and ketchup accordingly.

Mix and serve.

(This whole salad is 320 calories-2 cups spinach, one boiled egg, two slices thick cut baked bacon, 1 whole roma tomato, and 1 Tbsp grated parm.)
