Tomato Meatball Grinder Sauce Roasted Garlic Tomato Sub Sauce

I'm always looking for a great meatball sub
and find that they are a rare commodity.
I decided to make what I consider to be the
tastiest meatball grinder sauce
and I will share this with you here.

Ingredients:
2 large onions, chopped
2 (28 ounce) can crushed tomatoes
6-8 leaves fresh basil leaves
3-6 cloves garlic roasted
1 teaspoon salt
1 teaspoon ground black pepper
2 teaspoons olive oil
2 teaspoons butter

Directions:
In a large saucepan over medium-high heat,
add crushed tomatoes and raw quarted onions.
Add basil, garlic, salt and pepper.
When the garlic is done roasting add this as well.
Let the sauce come to a boil,
lower heat to low and stir occasionally until desired thickness.
Drizzle with olive oil part way through the simmering to taste.
Remove the big chunks of onion and just before serving add the butter.
Use on soft or crusty rolls with your favorite meatball recipe,
and fresh parmesan or mozzarella cheese.
