Description
Parmigiano-Reggiano adds salty, nutty richness to this ratatouille, which rivals the best oven versions. To speed preparation, feel free to skip the first step of salting and rinsing the eggplant and zucchini (this process draws off any bitter juices). Instead, just remove any particularly seedy and brown parts of the eggplant, or use smaller Japanese eggplants (which also do not need to be peeled). For pizzazz, add chickpeas and pitted, chopped oil-cured black olives. To make this dish vegan, swap in olive oil for the butter and skip the cheese (adding olives will make up for cheese's saltiness).
