Heat a large saucepan or dutch oven over medium heat.
Pour the Canned Whole Peeled Tomatoes (28 ounce) into a bowl and use your hands to break them up and crush them. You still want some bits of tomato. Set aside.
Melt the Unsalted Butter (2 tablespoon) in the pan. Once melted add in the Red Onion (1) and Kosher Salt (1/4 teaspoon). Cook until the onion is just softened, about 4 minutes.
Add in the Tomato Paste (1 tablespoon), Anchovy Paste (2 teaspoon), and Garlic (2 clove). Cook about one minute.
Pour the tomatoes into the pot along with the additional Kosher Salt (1/2 teaspoon).
Add in the Lean Ground Beef (8 ounce) and Mild Italian Sausage Links (8 ounce) and stir until well mixed in the tomato sauce. Cover with the lid and turn the heat down to a simmer. Cook for 20 minutes.
While the sauce is cooking, cook the Ziti Pasta (1 pound) according to package directions in a large pot of boiling salted water.
Combine the Shredded Mozzarella Cheese (2 cup) with the Grated Parmesan Cheese (1 cup) and Garlic Powder (1/4 teaspoon) in a bowl, mix with your hands and set aside.
After the pasta is done and the sauce is finished, drain the pasta and pour into the pan with the sauce. Mix well and then transfer half of the meat and noodle mix with a spoon into a 9"x13" casserole dish.
Sprinkle with half of the cheese mixture.
Preheat oven to 400 degrees F (205 degrees C).
Top with the remaining noodle and meat mixture. Then top with the remaining cheese.
Bake for 15 minutes then serve. Sprinkle with the Fresh Parsley (1 tablespoon) if desired.
