How to Make It
Cook the hot dogs according to the package directions.
Meanwhile, heat oven to 350° F. On a rimmed baking sheet, toss together the bread crumbs, parsley, oil, and ¼ teaspoon each salt and pepper. Bake until golden, 4 to 6 minutes.
Place a hot dog in each bun and, dividing evenly, top with the mac and cheese and the bread crumbs.
