I do love the texture of Greek yogurt, but I don't love how much more expensive it is than regular yogurt. Did you know that Greek yogurt is made by straining the whey off of regular yogurt, creating that thick creaminess. You can do that at home very easily.
If you let all of the whey strain out, they you have a product called yogurt cheese, which can be used in place of cream cheese. It is amazing spread on a whole wheat English muffin!
