In a large bowl, mix together the ground beef, bacon, egg, cheese, garlic, basil, parsley, salt, pepper and breadcrumbs. Mix until just combined - do not overmix! Form into 1-inch meatballs.
Heat a large skillet or dutch oven over medium heat and add 1 tablespoon of olive oil. Cook the meatballs in batches until golden brown on all sides, removing some to cook the others and adding more oil when needed. When all the meatballs are browned, reduce the heat to low, add in your marinara and add all the meatballs back into the skillet. Simmer for 10 to 20 minutes until the meatballs are cooked through.
While the meatballs are simmering, bring a pot of salted water to a boil and cook the bucatini according to the directions. Serve with meatballs and sauce - and parmesan cheese and fresh herbs!
