My Recipe Box - Sweet and Sour Stir Fry

DH wanted a stir fry last night, not one of my favourites to make. I like them in a restaurant but never seem to get a tasty sauce/gravy at home.
Also I was spoiled once we went to China and had the best ever meals there.

We had a top sirloin in the freezer, green peppers, onions and rice.
I found this recipe online and adapted it. It was not bad, I would use it again and perhaps add a little more soy and some Dijon mustard along with the yellow mustard.
Ingredients:

• 3 tablespoons brown sugar
• 3 tablespoons soy sauce
• 1/4 cup yellow mustard
• 1/4 cup ketchup
• Hot sauce to taste

Simply mix everything together and when your main ingredients are cooked pour this into the wok or pan.
