Yasai itame is what a Japanese diner cooks when you want vegetables and protein in one pan. Thin pork goes in first for flavour, then a mountain of cabbage, carrot, capsicum and bean sprouts hits the heat and collapses to about half its size.
The trick is heat and speed. The vegetables should stay squeaky and bright, so keep the pan hot, keep everything moving, and get it into bowls the moment the cabbage wilts at the edges.
