                                        Ingredients
2 tablespoons olive oil
▢1 large onion finely chopped
▢1 pound ground beef
▢1 tablespoon dried oregano
▢28 ounces crushed tomatoes
▢3 cloves garlic chopped
▢2 tablespoons tomato paste 
▢1 good sized handful fresh parsley chopped
▢Salt and pepper to taste
▢½ pound spaghetti
▢Grated Pecorino Romano or Parmesan cheese for serving optional
Instructions
Heat the olive oil in a large pan over medium heat. Add the onions and sauté until lightly golden, 2 to 3 minutes. Add the garlic and fry another minute.
Add the ground beef; fry until fully cooked and no pink shows at all in the meat (about 8 minutes). Add the oregano and tomato paste and mix with the meat.
Add the tomatoes, parsley, and bring to a boil. Season with the salt and pepper. Reduce the heat to low, and cook for at least 15 minutes (you can cook longer for a deeper flavor).
In the meantime, cook the spaghetti according to the package instructions. Drain and serve topped with the sauce and cheese (if using).
