For a slightly more elegant plating, the mushrooms tart is also nice in individual little shapes, with simply the dough and the veggies on top. And served with a little kabocha purée in a Parmegiano millefeuilles. 

The dough of the tart is again using a base of chesnut flour. For the kabocha purée I just washed and grilled under cover kabocha cut in pieces (with the skin), then mashed them with a fork. I then cut slices of vintage parmegiano and make layers of kabocha purée and parmegiano.
