Prep the cauliflower: (1) Remove outer leaves. (2) Cut into large florets. (3) Break apart into small florets with your hands or a knife. In a soup pot over medium-high heat, melt the butter in the olive oil. When the butter begins to sizzle, add the leeks and a pinch of salt. Sauté the leeks until they begin to wilt, about 5 minutes. Add the cauliflower and another pinch of salt, and cook the cauliflower and leeks until they start to come together, about 3 minutes longer. Add the Gruyère, and give everything a good stir. Add just enough chicken stock to cover the vegetables. Turn the heat down to low, and simmer until the cauliflower is tender, 20 to 30 minutes. At this point, the cheese will have mostly melted. Taste and adjust the seasoning, stir in the parsley, and serve hot.
