I LOVE Panera Bread's Asian Sesame Chicken Salad. This is a copycat recipe I found online for that dressing (doctored up a bit to use SB friendly ingredients):

2 tablespoons Splenda
2 teaspoons soy sauce (I used a reduced sodium version)
1 tablespoon sesame oil
1/4 cup vegetable oil (I used canola)
3 tablespoons rice vinegar (I used cider vinegar)

Combine all ingredients, shake, and serve!

I haven't had this on a salad yet, but I made it in a salad dressing shaker thingy (I know there's a more technically appropriate name for it!) and took a lick from the bottle, and it's quite good!

Mmm, that does sound good. Ever since I saw my mother's bottle of asian salad dressing in her fridge, I've been wanting to try some. Your recipe sounds really good!
