Uber Low Calorie Ranch Dressing

I saw this was posted before as a dip, but I love it as dressing! Make so many things taste better, better than store bought, AND pretty decent for you as well. Use less or more milk for consistency. Obviously, that will change the calories, etc. I'd start out with 1/4c. and see what you think for thickness.

1 c. Plain Greek Yogurt (I used Oikos)
1/2 c. milk (I used 1%)
1 packet ranch dressing (I used Hidden Valley - buy near dressings in store)

Mix with a whisk. Let sit for a few minutes at least for taste. Put into pourable container and go.

Here's the stats I got:
210 calories for the whole thing!
18 calories per 2 tablespoons
44mg sodium
0 choles (they say 2mg for the whole batch)
2 g protein
4 calcium
0 fiber
