Combine the meatloaf ingredients and thoroughly knead it with your hands. Grease a springform pan and press the ground beef mixture into the bottom and sides of the pan.
Mix the pasta sauce ingredients together, as shown in the video, and let the sauce simmer over a low heat for 10-15 minutes. Then stir in the cooked fusilli noodles.
Pour half of the pasta over the meatloaf, cover with cherry tomato slices, and sprinkle half of the mozzarella cheese on top. For the second layer, pour the remaining pasta over the cheese, and then sprinkle the remaining mozzarella on top.
Bake at 350°F for 35 minutes. Sprinkle scallion slices on top of the stuffed meatloaf for a garnish that's pleasing to the eye (and the stomach!).
