Ratatouille

This vegetable casserole brings together the natural sweetness of eggplant with the bright acidity of fresh tomatoes and green peppers, and the savory aroma of onions, garlic, and herbs. It's an extremely flavorful dish that pairs well with mild accompaniments like simply poached or roasted meats, seafood, eggs, or crusty bread. While it’s not a quick meal to prepare, it can be made ahead of time, reheated, served cold, or even frozen for later.

You can fry the eggplant and squash if you want. I like to roast the vegetables because it's faster, and uses less oil.
