Notes
You can add eggplants and alternate slices of tomato and eggplant slices. 
Mozzarella cheese can also replace Comté cheese. 
For a version with meat or fish: you can add slices of ham (between the mustard and the comté cheese) or tuna or anchovies.
For a vegan pie, remove the Comté and choose or make a pastry without butter.
