You don't need gloopy sauce. Here's a quickie for prawns & mixed veg for 4 people. You need 4 oz each of bean sprouts, bamboo shoots, mange tout, & carrots. (or substitute any for cauli, brocolli, peppers etc) and 8 oz prawns. Cut all veg into slices. Heat oil in wok. Add onions & cook for 1 minute. Add all veg except beansprouts and cook for 1 more minute. Add prawns & beansprouts. Sprinkle with 1 teaspoon of salt & 1 of sugar and 1 tablespoon of stock (or just water) Cook for 1 more minute. Done. Do not overcook or veg will lose flavour.
This assumes your prawns are cooked. If you are using uncooked prawns then continue cooking until they go from grey to pink.
When you've done this simple dish once you can change the recipe using other veg, and add cooked ham with the prawns or play to your hearts content.
