I love the stir-friend ong choy / phak bung (Thai: ผักบุ้ง according to Wikipedia) with garlic and chilis at Rod Dee. It's water spinach, the one with both crunchy stem bits and soft leafy bits. Goes great with the meat-heavy pad kra pao with beef. But they never seem to have them in stock these days. Any place you'd recommend so I can get a regular fix?
While "researching" for this post, I found an old thread about pea pod stems, which I also love but isn't the same veg. At least I don't think it is.
