1 Halve the chile pepper lengthwise, remove seeds and chop coarsely.
2 Peel the onions and garlic and chop finely.
3 Strip the kale leaves from the tough stems.
4 Heat a wok over high heat. Pour in the oil and swirl to coat. Add the garlic, chile peppers and onions and stir-fry until tender, stirring, about 1 minute.
5 Rinse kale, then add to wok with water still clinging to the leaves and stir-fry for about 5 minutes.
