There's just something about soup that makes winter Not So Bad. Especially when it is an easy peasy potato blue cheese soup that blends together into a creamy, hearty, cheese bowl of warm delicousness. Such is the case with this recipe, which cooks up all in one pot, and then gets whirled in the blender until it is smooth and thick and dreamy, and is just perfect for a cold winter's night. Or afternoon. I do love a good substantial soup for lunch...it gives me lots of energy to tackle the rest of the day. This one has three of my favorites in it: potatoes, leeks and a snappy blue cheese, and I always purposely make extra so that I can have it lunch after lunch. Let's make some!
