I fell in love with the Vanilla Chai Tea:
It's a soy protein drink, and it is delicious. It doesn't taste like milk, and it is very sweet and filling. I can easily drink a glass for breakfast and feel full till lunch time.
From the site: Our Perfectly Protein® Vanilla Chai Tea is a smooth blend of soy protein, brewed green tea, and chai spices all naturally sweetened with a subtle hint of vanilla. In addition to energizing the body with a heart-healthy supply of protein, this delicious drink is brimming with nutrients like Vitamin C, B6 and B12, iron, zinc, magnesium, 18 amino acids, and 37 grams of isoflavonoids per serving.Hazelnut Latte and Mocha Cappuccino are two other great flavors (but will make you use the bathroom something serious)
For those who might not like a milk like consistency, they have other flavors also.
