Zucchini and squash Au Gratin

I was really craving Au Gratin potatoes today so I decided to use squashes instead. It turned our magnificently!

Ingredients:
3 med zucchini
3 med yellow squash
1 onion
1 cup shredded cheese
1 Tbsp olive oil

Slice the vegetables thin. I dried them on a paper towel for 10 minutes. Pour and coat baking dish with oil. Arrange zucchini and squash in pan. I had the kids line them yellow-green-yellow-green :). It kept them busy and looked so pretty! Sprinkle on top sliced onions and cheese. Bake at a 425 oven for 20-25 minutes. Serve warm. Delicious!
