There are several brands of Greek yogurt on the market. You should definitely be able to find it in specialty markets like Whole Foods, Trader Joe's, Earth Fare, and The Fresh Market but check your local grocery store too. That's where I buy mine. Try out several brands and pick your favorite. I prefer Oikos by Stoneyfield Farms. Oikos has 0% fat and comes in two sizes—a large tub (16oz.) and an individual serving size (5.3oz.). The large-size tubs come in two flavors—vanilla and plain. The smaller size comes in plain, vanilla, honey, and blueberry. The smaller cups have just 90 calories, twice the protein of regular yogurt, and less carbohydrates.
I discovered Greek yogurt about a year ago and have been using it ever since. I had read an article about how you could use Greek yogurt as a substitute for sour cream in baked potatoes. I use the 0% fat version and it really does taste great as a sour cream substitute. Even my kids like it. You don't feel as guilty loading that potato when it's full of protein and fat-free. Greek yogurt also tastes great by itself as well as topped with fresh fruit. I make a killer Protein Breakfast Smoothie using Greek yogurt (click here for the recipe). It's also great with oatmeal. Try it in the Ultimate Power Breakfast (click here for the recipe).
