• 2 Italian sausages

Slice sausages lengthwise, leaving links attached along one side; lay flat in a large skillet. Cook over medium heat until browned and cooked through, 5 minutes, flipping once. Transfer to a plate; set aside.

• 8 oz (230 g) lean ground beef
• 0.5 onion, chopped
• 1 clove garlic, chopped
• 1 ¹⁄₂ tsp (7 g) extra-virgin olive oil

Add ground beef, onion, garlic, and olive oil to the same skillet over medium heat; cook and stir until onion is translucent and beef is browned and crumbly, about 10 minutes. Drain all but 2 tablespoons drippings from the skillet.

• 7.5 fl. ozs. (230 g) tomato sauce
• 7.25 fl. ozs. (218 g) whole peeled tomatoes

• ¹⁄₂ tsp (0 g) dried basil
• 0.5 bay leaf
• ¹⁄₈ tsp (0 g) black pepper

Stir in tomato sauce, tomatoes, oregano, salt, basil, bay leaf, and black pepper; simmer, uncovered, over low heat until flavors have blended, about 1 hour, stirring occasionally. Remove and discard bay leaf.

• 8 oz (230 g) spaghetti

Preheat the oven to 350 degrees F (175 degrees C). Bring a large pot of lightly salted water to a boil. Cook spaghetti in the boiling water, stirring occasionally, until tender yet firm to the bite, 8 to 10 minutes. Drain.

Divide spaghetti and sauce among individual oven-safe baking dishes or plates; top each with a cooked half sausage and sprinkle with Parmesan cheese.
