Firm, meaty white fish fillets are perfect for stir-frying as they keep their shape well and don't break up easily. Serve the fish on a bed of tender vegetables and top with salty prosciutto, all cooked in the same wok. Some crusty bread rolls would complete the meal nicely.
Heat 1 tablespoon of the oil in a wok or large frying pan until very hot, then add the fish pieces. Stir-fry for about 5 minutes until lightly browned all over and cooked through. Remove from the wok and keep warm.
Add the prosciutto to the wok and stir-fry over a fairly high heat for 1-2 minutes until golden and crisp. Remove and keep warm.
Add the remaining oil to the wok and stir-fry the garlic, ginger and chili pepper for about 30 seconds, without browning. Add the scallions, snow peas and beans and stir-fry for 3-4 minutes. Stir in the bokchoy and stir-fry for about 2 minutes until the leaves are wilted.
Pile the vegetables onto warmed serving plates, place the fish pieces on top and add a few crisp pieces of prosciutto. Drizzle with the soy sauce and serve immediately.
Variations: A vegetarian version could be made with chunks of firm tofu. Lightly fry it in half the oil, then continue from step 3 as in the recipe. Pile the tofu on top of the vegetables and drizzle with soy sauce to serve. If bokchoy is not available, you can use roughly shredded napa cabbage.
