Since making this recipe originally, I have made it again and left out the stevia altogether. It still tastes great. You really only need the buttermilk for thinning the dressing. Otherwise it is the thickness of sour cream - obviously. You use less if it is thinner.

I like it on plain spinach. It would be even better with crumbled crispy bacon as well. Think I'll make some today and buy some spinach and bacon.
