Arrange buns poppyseed side down on a cutting board in a large square shape with the edges slightly overlapping.
Flatted buns with a rolling pin to help them stick together.
Place a round bowl or plate over the buns and trace around it with a knife so you're left with a circular crust.
Place a pizza pan over the crust and flip the cutting board upside down so the crust is now poppyseed side up on the pizza pan.
Spread pizza sauce evenly over the crust and top with shredded mozzarella cheese.
Slice hot dogs into ¼" thick slices and add them to the pizza.
Bake pizza in the oven for 10 minutes at 350° or until the cheese is melted.
Add sport peppers, diced tomatoes, pickles, diced white onions and sweet pickle relish, sprinkle with celery salt and drizzle with yellow mustard.
