Eat your lasagna and have your vegetables, too, with a veggie-enhanced rendition of a family favorite. This layered gratin resembles a lasagna, with one key difference: There are no pasta sheets.

Roasted eggplant, zucchini, and yellow squash slices keep this dish light and colorful, alternating with a bright tomato sauce and fluffy ricotta. Shutterstock
