Sa phak ruam or sa phak phae is a spicy vegetable salad of an assorted kind of greens mostly foraged from the wild such as indigofera, suberosa, mimosoides, concinna. Nowadays, the tender greens of Chinese mustard greens (1-2 week-old sprouts) are included as they are mostly available in the local markets, especially from April-May which is considered a tropical springtime.
