The other Greek yogurt that Costco carries that we LOVE is FAGE. It is unflavored and we use it as a sour cream replacement.
Has the same consistency and almost the same flavor as full fat sour cream. It has 0 fat, lots of protein and is 0 weight watchers points until you get up to 1/2 cup.
It is super used as sour cream replacement in beef stroganoff, mixed with a little salsa and put on tacos...the uses are endless!!
sorry for the tangent...can you tell we love FAGE??
