Bolognese Sauce

Warm oil in a large skillet over medium heat. Sauté onion, bacon, and garlic in hot oil until bacon is browned and crisp, about 10 minutes. Use a slotted spoon to transfer bacon mixture to a paper towel-lined plate to drain; set aside.

Place the same large skillet over medium-high heat. Cook and stir ground beef and pork in the hot skillet until browned and crumbly, 5 to 7 minutes. Drain and discard grease.

Stir bacon mixture, tomatoes, mushrooms, tomato sauce, carrots, celery, wine, stock, basil, oregano, salt, and pepper into meat mixture. Bring to a boil. Cover, reduce heat, and simmer sauce for 1 hour, stirring occasionally.
