This recipe uses Frescolio Basil EVOO. You could also try it with Herbes de Provence EVOO or Tuscan Herb EVOO for a different taste. As a nice finish, try drizzling the Ratatouille with Fig or Traditional Dark Balsamic vinegar before serving. You might also want to try this with Salish Smoked Sea Salt, available in store.
If you are not a fan of eggplant, a great substitute would be zucchini.
A traditional ratatouille does not include cheese, although you can add some if you want. Try adding some shaved Parmesan or Asiago for the last 10 minutes of roasting.
