In a medium- sized pot add the olive oil, garlic, chopped carrot, onion and celery, cook on medium heat for approximately 2-3 minutes or until the onion is transparent.
Add the ground beef and brown, then add the puree, water, salt, oregano, basil, fresh basil leaves, bay leaf and hot pepper flakes (or black pepper) if desired, stir well to combine. Bring to a boil, then lower heat and simmer half covered for approximately 35-40 minutes or until desired thickness, stirring occasionally. Remove the bay leaf.
Serve over cooked fettuccine or pasta of choice, sprinkle with freshly grated parmesan cheese if desired before serving. Enjoy!
