Not my Not Recipe: Ratatouille in galette format!! My friend Mike mandolined zucchini and summer squash and layered it in a cast iron pan with homemade tomato sauce and Parmesan cheese with lots of good olive oil, salt and pepper. Bake in oven at 400 for 20 minutes, or in a slower oven for longer. The key is that when you are done, the veg should be soft and taste delicious and mix nice with all of its pals in the pan. Finish under the broiler as needed (add more cheese?? I'm not telling Mike what to do!) for a nice crust and some color.
