I recently discovered this Silk Unsweetened Vanilla Almondmilk yoghurt, and I'm hooked. It's thick and creamy, and it tastes slightly sweet even though it's unsweetened. It's also soy-free, which I prefer because I eat so much tofu and tempeh; it's good to mix up my protein sources. A one-cup serving offers seven grams of protein.
