Zucchini and Potato Healthy Gratin

Potatoes are one of my favorite ingredients because they are so varied and you can cook them in so many ways. Today I decided to make a Zucchini and Potato gratin as I wanted something healthy but a bit crunchy - a dish that makes you feel cozy and gives you the feeling that you are treating yourself to something nice while being healthy and nutritious. I made the gratin with parmesan, breadcrumbs and herbs using no cream or milk as this is what makes the dish heavy.
