Pour olive oil in a large stock pot. Heat to high and add the minced garlic and diced onions. Cook for 1 minute until lions begin to turn translucent (stir often).
Then add in the crushed tomatoes, petite diced tomatoes, and tomato paste. Reduce heat to medium-low and mix well. Sprinkle in the Italian seasoning, dried basil, salt, black pepper, and sugar. Mix well again and place the lid on the stock pot. Reduce to low and simmer for 25 minutes. Stir often to ensure the sauce doesn't stick or burn to the bottom. Serve with your favorite pasta.
Notes
Make this sauce your own (and even easier) by purchasing seasoned tomatoes and skipping measuring out seasonings.
