Hi. While the picture that you posted is a vegetable, which has the same root as vegetarianism, this is not a Q&A for identifying vegetables and as such, your question does not belong here.

Hello and welcome to Veganism & Vegetarianism Stack Exchange site.As your question is not really related to vegetarianism, it is considered off-topic here.

I think you meant to ask this of the Cooking Stack Exchange site... they have a food identification tag that this would probably fall under (https://cooking.stackexchange.com/questions/tagged/food-identification)
That having been said, according to this, it's Gai Choy: http://greenandfreshtx.com/unique-asian-vegetables/
