Marinara sauce (or Pizza sauce)

I made this recipe for when we made homemade pasta and it was a hit but we decided that it made a really good pizza sauce too.

 Ingredients:
2 (28 ounce) cans stewed tomatoes
1 (6 ounce) can tomato paste
4 tablespoons chopped fresh parsley - 3 tsp dried
4 clove garlic, minced
2 teaspoon dried oregano
2 teaspoon salt
124 teaspoon ground black pepper
6 tablespoons olive oil
2/3 cup finely diced onion
1/2 cup white wine

With most of this seasonings I added a decent amount more than recommended but of course everything is to taste so add the amount suggested and go from there.

1. In a food processor place Italian tomatoes, tomato paste, chopped parsley, minced garlic, oregano, salt, and pepper. Blend until smooth.
2. In a large skillet over medium heat saute the finely chopped onion in olive oil for 2 minutes. Add the blended tomato sauce and white wine.
3. Simmer for 30 minutes, stirring occasionally.
