What may be my personal favorite is the Premier Protein Strawberries and Cream flavor. It does a great job of offering a sweet taste without having that chalky taste that some other protein shakes have. It almost tastes like strawberry milk. Its very cream and goes down smooth.
At two carbs per shake you can't beat that and it has a bunch of vitamins in it to help you get what you need. It's probably not going to fill you up by itself, but with a small snack you could easily make this a meal.
I should mention that the Costco near us stocks these in bulk if you want to save a little money and stock up.
