1 packet ranch seasoning
1 17-oz. container Greek yogurt (I got FAGE at ALDI for $3.29)
= YUMMY ranch dip that tastes like sour cream
This recipe is different than just eating it plain. It's highly seasoned, so you're using Greek yogurt mainly for the thickness and texture. I had my dh try it and he didn't even realize it was yogurt and not sour cream! I'd think with regular yogurt it would be too runny. If you do try it with regular, strain the yogurt first. I've done this before with a coffee filter and it works well.
Unfortunately, it's really defeating the purpose of eating healthy if you are using the ranch powder, because it contains MSG. I try to not EVER give my family MSG laden foods, but unfortunately 99% of the ones at the store have it. Try, Newman's Ranch. There is no MSG in that one. The greek yogurt, however, is always a wonderful alternative to sour cream in almost any dish that calls for sour cream.
