How do you say vegetarian in Chinese?

The adjective (as in vegetarianfood) would be 素食 su4shi2 (pinyin romanization). The verb form, which doesn't have a one Word translation, would be 吃素 chi1su4, literally eat vegetarian. One would generally refer to oneself as a vegetarian by using the verb form - 我吃素 wo3chi1su4 - literally I eat vegetarian.
