Even before I became a vegan, before I really started cooking, I wanted to make ratatouille the way Remy and Linguine made it. Thin slices of courgette (zucchini), aubergine (eggplant), et poivron (pepper) snuggling in a bed of tomato puree infused with garlic, onion, and thyme... I was singing Le Festin almost the entire time it was in the oven.
I highly recommend small variety eggplant - not just because it stacks better with the zucchini, but because they aren't as bitter. Large purple eggplants work well enough, but they have to be peeled and "sweated" first.
Mandolines are wonderful, but they always shred my eggplants :-( No matter how much confidence you lack, you can probably get a more uniform cut using a sharp knife.
Since all of my veggies were smaller than I'm used to, I doubled the recipe, making four people happy and one person unhappy (the 14-year-old was not a fan).
It always surprises me how much vegans can eat. This was my optimistic first helping. The second was much bigger :)
