Soy milk can be really super delicious. Some's a tad bitter though; it's important to pick a brand that suits your taste.
When I first tried soy milk, I was at my friend's house; his entire family is more or less lactose intolerant so I didn't have much choice but to down the stuff, which, ironically, I found extremely unpalatable. I guess soy milk isn't something you can jump right in to. Too bad, because it's really quite nutritious.
I don't eat meat but I'm not vegan, I just don't eat meat, you see. Soy milk is an abundant source of proteins and vitamin E, if you can get past the taste.
Eventually I was introduced to the delight of chocolate soy milk, which eased me into the whole soy milk phenomenon. I started brewing chai tea in 'Silk' brand vanilla soy milk, which is very likely the most scrumptious thing in the world. It's very filling and warm and homey. My chai tea mostly consists of "sweet" spices such as cloves and nutmeg and ginger and cinnamon, and Earl Grey tea, and honey. Maybe vanilla, which makes the tea vanilla on vanilla on ambrosia.
