What kind of dish is a gratin?
user
A gratin is a baked dish that typically has a layer of vegetable on the bottom and a layer of cheese on top.
assistant
Oh, that sounds good. What kind of vegetables can you use?
user
You can make many different kinds of gratin with different types of vegetables.  When you add cheese on top, you’re making a quiche.  So if you’re interested in making one of those, you could try the various varieties of potato, sweet potato, tomato, zucchini, asparagus, green beans, and broccoli.  (They’re also often called quiches.)
assistant
I'm not sure that's correct though. I think a quiche is basically an egg dish.
user
I’m not sure, sorry. I’ve never heard that one before.

You’re right, you don’t want to cook a quiche in the oven, but it’s an excellent choice for a gratin.  Gratins are a lot like quiches, and both include cheese on the top of the vegetable.  An easy way to make sure you’ve got a true gratin is to make sure the top of the dish is a lot higher than the bottom.  That will ensure that it’s a gratin and not a quiche.
