INGREDIENTS:
1 tablespoon olive oil
1 onion, chopped
1 clove garlic, chopped
1 (14.5 ounce) can peeled and
diced tomatoes 1 (8 ounce) can tomato sauce
1 teaspoon white sugar
1/2 teaspoon dried oregano
1/4 teaspoon salt

DIRECTIONS:
1. Heat olive oil in a saucepan over medium-high heat. Add onion and garlic and cook 2 to 4 minutes until crisp-tender, stirring frequently.
2. Mix in diced tomatoes, tomato sauce, sugar, oregano and salt. Bring to a boil. Reduce heat to low and simmer 15 to 20 minutes or until flavors are blended, stirring frequently.

I'm sure you could add ground meat if you wanted to make a meat sauce.
