This is my mother's recipe for ratatouille, given to me almost 30 years ago. It makes wonderful use of the summer harvest of eggplant, tomatoes, green peppers and zucchini. It is delicious, colorful, and very versatile. It goes great as a side dish, with some cold roasted chicken, in an omelette, over pasta, or even in a sandwich! I don't know why, but I find this tastes even better a day later. I guess it gives the flavors a chance to really marry.
