Zucchini Tomato and Rice Gratin

This recipe is easy but I found it labour intensive. After oven-roasting vegetables, cooking grains, grating cheese, and sautéing onions and garlic, it then comes together quickly and is baked in the oven. If I make this again I would make some of the components ahead. I subbed quinoa for the rice and used a mixture of good quality cheddar and smoked mozzarella as the cheese and also increased the cheese somewhat. I found this was a nice way to eat zucchini and it had a very mild flavour that probably most people would enjoy. Could be eaten as a brunch, lunch, or dinner dish. While this recipe was fine, I probably won't make again.
