I looked this one up online, then made it, and WOW, just like the stuff you get on your salad before your haibachi dinner!!! (next is the hunt for that soup!)

I even entered it into fitday to calculate the carbs for you. I'm sure if you substitute low-carb ketchup it would be even less! I use this on salad, dip 1/2 cup raw green beans into it as a snack, and even smother it on tuna steaks!!
Enjoy!

1/2 cup minced onion
1/2 cup peanut oil
1/3 cup rice vinegar
2 tablespoons water
>>>>>(at this point I purreed the mixture)
2 tablespoons minced fresh ginger
2 tablespoons minced celery (I think I accidentally ommitted this)
2 tablespoons ketchup
4 teaspoons soy sauce
2 teaspoons sugar (I used one packet of splend instead)
2 teaspoons lemon juice (used fresh)
1/2 teaspoon minced garlic (used a bit of garlic powder)
1/2 teaspoon salt (really to taste)
