Making Stuffed Cannelloni with Minced Meat and Tomato Sauce can be fun if you follow these simple steps:

1. Cook the Cannelloni: Bring a large pot of salted water to a boil. Add the cannelloni tubes and cook until al dente. Drain and rinse under cold water.
2. Prepare the Filling: In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until translucent. Stir in minced garlic and cook for an additional minute.
3. Cook the Meat: Add the minced meat to the skillet. Cook thoroughly, breaking it apart, until browned. Season with oregano, basil, salt, and pepper.
4. Fill the Cannelloni: Using a spoon or a piping bag, fill each cannelloni tube with the meat mixture. Be generous for maximum flavor.
5. Prepare the Sauce: In a large saucepan, heat the tomato puree over medium heat. Add additional herbs, salt, and pepper to taste. Bring to a gentle simmer.
6. Assemble the Dish: Spread a layer of tomato sauce on the bottom of a baking dish. Arrange the filled cannelloni on top. Pour the remaining sauce over the cannelloni and sprinkle with Parmesan and mozzarella cheese.
7. Bake: Cover the baking dish with aluminum foil and bake at 375°F (190°C) for 30 minutes. Remove the foil and bake for an additional 15 minutes or until the cheese is bubbly and golden.

Following these steps ensures that your meal is not just easy to prepare but also profoundly delicious—a real winner in the kitchen.
