Rinse mussels under running water. Tap mussels on the edge of the sink; discard those that do not close. Leave the rest in cold water.
Peal and finely chop the shallots and garlic; finely chop the celery, leek, and carrots. Chop the butter into cubes and divide. Saute vegetables in half of the butter for about 3 minutes; add white wine, bay leaf, and thyme and bring to a high heat. Add mussels and cook on high for five minutes, shaking occasionally. Remove thyme and bay leaf. Bring cooking liquid to a boil and add the remainder of the butter, whisking. Serve with chopped fresh parsley.
Preheat oven to 180C. Cut the zucchini in half lengthwise, and remove the innards with a tea spoon, leaving 1/2 cm of flesh before the rind. Chop the innards fine and mix with the creme fraiche and sage. Season to taste with pepper and salt.
Grease a baking dish. Lay in the zucchinis, and fill with the creme fraiche/zucchini mixture. Sprinkle with cheese and pine nuts. Bake 20 min. until golden brown.
