Is quiche Lorraine suitable for vegetarians?

No, it contains a little bit of meat (ham or bacon). If you're vegan and don't have any animal products whatsoever than it wouldn't be a good choice cause it has egg and milk in it too (like all quiches)

Quiche Lorraine contains ham. There are similar quiches without meat, but they still contain eggs, milk and cheese.

Yes.~ There is spinach quiche,my favorite or broccoli quiche also good.~*

As far as I know it contains bacon so it wouldn't be suitable.

If you have it with just cheese and eggs as the main ingredients,then it's fine.

it is perfect because it does not contain no animal products but i am leery of the eggs and the milk in which it is cooked in

We are all taught that there are no dumb questions. Good for you for proving there are.

Sometimes, it sometimes contains meat.
