It's Tuesday...time for a Mighty Good Recipe. I've made this one a few times and it's always well received. It's a great side dish and goes with just about anything. I know it's the wrong time of year, but zucchini gratin is also a nice alternative to some of the common side dishes for Thanksgiving. Sometimes I'll make this instead of green bean casserole. And one last thing...any dish that contains a good amount of Gruyere has about a 95% chance of of achieving awesomeness.
