I have just finished eating stir fried veg with noodles in my very own home made sauce! It's one of my fave's (and I'm not a vegetarian!) and it takes minutes to do! For the veg I sliced onions, peppers, carrots, mushrooms and broccoli and for the sauce mixed equal parts soy sauce, sherry and water, then added crushed garlic, grated ginger, black pepper, a pinch of 5 spice and the same of sugar. Mix a bit of cornflour in water and throw that in too! Stir fry your veg until its almost cooked, add your pre-mixed sauce, allow it to bubble for a few secs (add more water if too thick), then add your (cooked) noodles and mix it all together. Enjoy!
Sorry about the lack of quantities - I tend to cook by eye!
