Preheat a lightly oiled grill over medium high heat. Meanwhile, melt butter in a large pot over medium heat. Sprinkle flour over butter and whisk until golden. Stir in milk and bring to a simmer. Gradually whisk in mozzarella cheese and 1/3 of the Parmesan cheese until melted. Season with salt and pepper and add Elbows; toss to combine.
Trim the bottom of each of the hollowed tomatoes so that they stand straight without rolling. Season tomatoes with salt and pepper. Divide mac n’ cheese and tomatoes; sprinkle with Parmesan cheese, chili flakes (if using), oregano and breadcrumbs.
Arrange tomatoes on the grill and cook for 15-18 minutes until charred and heated through. Let tomatoes rest for 5 minutes before serving. Serve alongside a green salad.
