In a large saucepan, heat olive oil over medium heat.
Add garlic, reduce heat to low, sauté until garlic is softened, but not brown.
Pour tomatoes into a bowl and squeeze with hands to break up. Add tomatoes and juice to the pan. If prefer, pulse several times in a blender rather than using hands.
Add salt, pepper and red pepper flakes.
Simmer on low and let simmer for 40-45 minutes until thickened. If starts to become too thick, add water, a few teaspoons at a time.
Taste for seasoning and add if needed. Option to add a few pinches of oregano.
Use on your favorite pasta or vegetables and top with fresh chopped basil.
