Squash Gratin

I don't think this is really a gratin. I think gratins have more cheese and maybe cream added, so I'm not sure what this is really, but it good!

Squash Gratin

1 large potato
1 yellow squash
1 zuchini
hanful of grape tomatoes
1/4 cup olive oil
1/4 cup fresh grated parmesan cheese
plenty of salt and pepper
herbs if you like: rosemary, thyme, oregano whatever your favorite!

In a nice baking dish or pie plate, pour a bit of oil and rub it all around. Peel and slice your potato in very thin rounds. Make a layer of potato around the bottom. Sort of like a crust. Slice squash and zuchini in equal size rounds. Carefully place them artfully around your dish. Top with sliced tomatoes, the rest of the olive oil, the parmesan and seasonings. Bake at 425 for 25 minutes until top is nice golden brown and potatoes are cooked through.
