Cannelloni with vegetables fantasy

I didn't prepare some special cannelloni, I worked hard only on the creative side of the filling.
And I had the following ideas, for 3 persons:

1 broccoli, boiled - 25 minutes
1 eggplant - fried - 15 minutes
5 potatoes, mashed with 2 nails of butter
The final mixture is filling the cannelloni to which you can add a good white wine.
