Subway's Meatball Marinara Sauce

I like the subway meatball sandwiches and
always tried to make my own at home.
The main tastes are oregano and sugar.
Here is the recipe that I came up with.
Make your own meatballs to go with it.
I Like to make this with turkey meatballs.

Ingredients:
1 onion, peeled and finley chopped
4 garlic cloves, peeled and minced
2 cups canned crushed tomatoes
1/4 cup cold water
1/2 teaspoon red wine vinegar
1 teaspoon white sugar
1 teaspoon brown sugar
2 teaspoons dried oregano
2 teaspoon olive oil
1 dash of salt

Directions:
In an oiled skillet, combine the onion and garlic.
Cook, stirring occasionally with a wooden spoon,
for 3 to 5 minutes, or until the onion
starts to soften but not brown.
Reduce the heat to low.
Add the tomatoes, water, sugar, oregano and oil.
Stir to blend all ingredients well and
cook on a low simmer for about 30 minutes.
Refrigerate up to 1 week until ready to use.
