Rice, Corn and Mushroom Gratin

While growing up in Colombia, my aunt was always making a rice, chicken and mushroom gratin and I really enjoyed it. So a couple of weeks ago when I saw organic mushrooms in my fridge, I decided to make a vegetarian version of her dish.

It ended up being really tasty! A great side for a fall day or for your Thanksgiving dinner party. Feel free to add 1 cup of shredded chicken or chopped ham for a non-vegetarian version.

Buen provecho!
