A Ripple Farm "stir-fry bag" came in my vegetable box this week. It contained broccoli, a few very thin leaks, and various leafy vegetables I could not identify.
Recipes tell you to heat the oil for stir-fries until it is smoking. Don't, unless you want to consume burnt oil. I put a Le Creuset casserole (I don't own a wok) on a medium heat for a few minutes, before pouring in a couple of tbsps sunflower oil. Immediately, I threw in the washed and drained greenery, and turned up the heat, stirring everything around rapidly until it wilted - no more than a couple of minutes. I stirred in a few shakes of soy sauce, divided the contents of the pan between two plates, and laid sliced goat's cheese on top. That was it.
