I found this recipe some time back and printed it off but didn't reference the source.  I came across it this past week when I was weeding through my recipe drawer looking for an easy week night meal. 

This was very good.  It was easy to prepare and Serena liked the noodles with the sauce (though she picked around the sugar snap peas).  It wasn't PF Chang's, nor authentic, but it was a fulfilling meal with an Asian twist.

Asian Beef with Noodles

8 ounces uncooked spaghetti, broken in half
3 cups fresh sugar snap peas
1 cup thinly sliced sweet red pepper
1/2 cup Catalina salad dressing
1-1/2 pound top sirloin steak, cut into thin strips
2 Tablespoons creamy peanut butter
2 Tablespoons soy sauce
1/2 cup thinly sliced green onions
1/2 cup dry roasted peanuts

In a large saucepan, cook spaghetti according to package directions, adding the snap peas and pepper during the last few minutes of cooking; drain.

Meanwhile, in a large skillet, heat salad dressing over medium-high heat.  Add beef, cook for 8-10 minutes or until meat reaches desired doneness.  Add peanut butter and soy sauce; cook for 2 minutes or until thickened.  Stir in spaghetti mixture and onions; sprinkle with peanuts.
