In a large skillet, heat a drizzle of olive oil over medium heat.
Add the chopped onion and minced garlic, and sauté until they become fragrant and the onion turns translucent.
Add the ground beef (or your choice of ground meat) and cook until it's browned and no longer pink. Break it up into small pieces as it cooks.
Stir in the crushed tomatoes, tomato sauce, dried oregano, dried basil, salt, and pepper. Let the sauce simmer for about 15 minutes, stirring occasionally, until it thickens.
