BEST MARINARA SAUCE YET
Adapted from Allrecipes.com
2 (14.5 ounce) cans stewed tomatoes (you can also used diced tomatoes)
1 (6 ounce) can tomato paste
4 tablespoons chopped fresh parsley (or 4 tsp. dried)
1 clove garlic, minced
1 teaspoon dried oregano
1 teaspoon salt
1/4 teaspoon ground black pepper
6 tablespoons olive oil (we cut this back to 3-4 Tbsp.)
1/3 cup finely diced onion
1/2 cup white wine (we substituted chicken broth)
In a food processor place Italian tomatoes, tomato paste, chopped parsley, minced garlic, oregano, salt, and pepper. Blend until smooth.
In a large skillet over medium heat sauté the finely chopped onion in olive oil for 2 minutes. Add the blended tomato sauce and white wine/chicken broth.
Simmer for 30 minutes, stirring occasionally.
