Basic Tomato Sauce

I've never made my own pasta sauce, and I found this one on
http://stephaniecooks.blogspot.com/ and I want to try it soon!

Ingredients:
2 Tablespoons olive oil

1 tablespoon of onion powder (or 1 small sweet onion, chopped)
6 cloves garlic, crushed
2 28-oz. cans of crushed tomatoes

2.5 teaspoons dried parsley

1/2 teaspoon dried basil


2 teaspoons salt

2 Tablespoons sugar
Red pepper flakes (if you want it hot)

Directions:
1. Saute onion and garlic in olive oil over medium-low heat until onion is tender.
2. Add crushed tomatoes, parsley, basil, salt, and sugar.
3. Stir and lower heat to a slow simmer.
4. Allow to simmer for 2-3 hours at a minimum. About 1 hour before done simmering add the red pepper flakes.
