The Sweet Onion Chicken Teriyaki Sandwich is one of Subway's biggest new product rollouts in chain history. The sandwich is made with common ingredients: teriyaki-glazed chicken breast strips, onions, lettuce, tomatoes, green peppers, and olives. But what sets it apart from all other teriyaki chicken sandwiches is Subway's delicious Sweet Onion Sauce. You can ask for as much of the scrumptious sauce as you want on your custom-made sub at the huge sandwich chain, but you won't get any extra to take home, even if you offer to pay. Now you can add a clone version of the sauce to your home-built sandwich masterpieces whenever you want.

1/2 cup light corn syrup
1 tablespoon minced white onion
1 tablespoon red wine vinegar
2 teaspoons white vinegar
1 teaspoon balsamic vinegar
1 teaspoon brown sugar
1 teaspoon buttermilk powder
1/4 teaspoon lemon juice
1/8 teaspoon poppy seeds
1/8 teaspoon salt
pinch cracked black pepper
pinch garlic powder

1. Combine all the ingredients in a small microwave-safe bowl.

2. Heat the mixture uncovered in the microwave for 1 to 1 1/2 minutes on high until the mixture boils rapidly.

3. Whisk well, cover, and cool.

Makes about 2/3 cup.

This sauce is very vinegary. For 2/3 cup of sauce you're gonna use two tablespoons of vinegar. I only used a table spoon of red vine. The sauce came out really good. I'm gonna try a little pineapple juice to this to thin a chilled thickened version.
Love it!!

This is pretty close....I think doubling the brown sugar is helpful.

Nothing like Subway, but great!

I've been making this for months now... It tastes nothing like Subway sweet onion at all, I think, but still I absolutely love it. I can't eat dry sandwiches no more without having the bread soaked in this dressing. You have to let it soak through and get your bread all wet, then your sub will shine. I think it's important to note that you probably better off mincing your own fresh onions rather than buying them dried out in those spice bottles.

It's OK.... a little watery and tastes a little vinegary, but still good. You've done it again, Todd!

Nice taste but hardly like Subway. The consistency needs improving. Not sure if I would go to the expense to make it again. Thanks anyway!

This comes out just like Subway's and is so good on sandwiches! My main incentive for going to Subway was their specialty sauces, but now I can recreate the deli sandwiches at home, sauce and all. The Sweet Onion is great; I hope TSR adds the Honey Mustard!

GREAT! Comes out just like the stuff at Subway. I make several batches and can it so I can always have some on hand.
