@FrugalGramma- it was very flavorful, with everything together. I don't call them aubergine either- a British/European thing?
Eggplant is not everyone's favorite. If cooked well, it almost melts into the sauce, like tomatoes. A few of my eggplant chunks weren't done enough and still like a spongy cube, which I don't like. So I liked it, but next time would make sure I cook all the eggplant cubes enough before adding more to the pan, or cut them smaller. I think the eggplant is optional and it would be great just with zucchini.
I have plenty of ratatouille left and today plan to get some kind of white fish to cook in it.
I had fried okra also last night. Okra going gangbusters. If not cooking it that day, I just slice into a freezer container.
