Marinate beef strips (1/2 a kilo to 1 kilo depending on how many people) in half a bottle of sweet soy sauce and 4 turns of the salt grinder - leave for a minimum of an hour

Cook 2 to 4 packets of Mi Goreng noodles for about 2 minutes, you only want the noodles to separate not be soft and mooshy. If your serving 4 people I'd go with using 3 packets. You could also use the sachets from the noodles to put in your beef marinate depending on what ones you like. Once noodles are cooked drain out the water and put to the side.

Throw your stir-fry veggies in your wok (if you don't have a wok a big fry pan will do), you choose the veggies and the amount depending on what you like and how many people are eating. Swirl some more sweet soy sauce on-top and let cook for 3-4 minutes depending on fresh or frozen veggies, don't cook to long you don't want them to be soggy.

Now throw your marinated beef into the hot wok/pan with your veggies let cook for about 2 minutes then add your noodles.

Stir everything together for about 1 minute then turn of, you don't want to cook the beef strips for more then 4-5 minutes or they'll go tough and chewy.

You could use chicken if you wanted and even rice instead of noodles.
