In the same “class” as okra, winged beans are excellent when fried with sambal. This dish reminds me of some of the very tasty hilltribe food in Myanmar. It’s the opposite of Thailand where hilltribe food is often bad compared to the food at restaurants. In Myanmar, the simple hilltribe food is often better than the pungent, sour and oily stuff in the restaurants.
Winged beans are supposed to be crunchy, so don’t try to soften it too much.
