For the vegetables:
In a saucepan over medium heat melt the butter and cook the sage for a few minutes. Add leeks, pumpkin and cauliflower florets and coat in butter; cook for 5 minutes. Season with salt, pour 240ml of vegetable stock and cook until the vegetables are just tender, about 10 minutes, adding more stock if the mix gets too dry. Season with pepper, remove from heat and set aside.
For the bechamel sauce:
In a saucepan over a medium heat bring the butter and 300ml milk to the boil. Meanwhile, in a blender mix the remaining milk, flour and salt. Add to the saucepan and simmer for 5 minutes, whisking often until it thickens enough to coat the back of a spoon. Remove from heat, season with salt and nutmeg and stir in the grated Gruyere cheese. Set aside.
Preheat the oven 180 C / Gas 4. Grease a 26X20cm baking dish with butter.
For the lasagne
If using fresh lasagne sheets, bring a large saucepan of lightly salted water to the boil and dip each lasagne sheet in the water for 1 minute, or as specified on the packet, then drain and pass quickly under the cold tap to stop cooking. Lay them on a tea towel and pat dry. If using dried, ready to bake lasagne sheets, skip this step.
Spoon a ladle-full of the bechamel sauce over the bottom of the baking dish. Lay some pasta sheets side by side and cover with some white sauce; then add some vegetables and sprinkle with some grated Parmesan cheese.
Continue layering, proceeding the same way and making as many layers as your ingredients allow (about 3 or 4) and finishing with bechamel sauce and a good handful of grated Parmesan cheese on top. Distribute few butter curls on the top.
Bake for 35 minutes or until the pasta is fully cooked and the top is golden brown. Remove from oven, then let stand for 10 minutes covered with an aluminium foil before slicing and serving.
