First, heat the EVOO in a large saucepan over medium heat.
Add the finely chopped onion and garlic.
Sauté them until they are soft and fragrant, which usually takes about 5 minutes.
Next, add the crushed tomatoes and bay leaves to the saucepan.
Rinse the tomato cans with 2 cups of water and pour it into the pan.
Bring the mixture to a boil, then lower the heat to maintain a lively simmer.
Add the crushed red pepper flakes, and season with salt and pepper to taste.
Let the sauce cook, stirring occasionally, until it thickens.
Remove the bay leaves before serving and, if you like, garnish with fresh basil.
