It sounds like a complicated French dish, but really it's just a simple summer casserole with a beautiful presentation. It does take a little time, but the results are well worth it! Using a plethora of tomatoes, squash, eggplant, zucchini, and herbs harvested from your summer garden, this dish is sure to impress at your next cookout or potluck. It can be scaled up or down depending on your pan size (or harvest size). Bon appetit!
