- Place the bottom half of the buns in a large (13x9-inch) foil-lined baking dish. (You can lightly grease the foil before adding the buns.)

- Cut the hot dogs in half lengthwise and then cut them again into halves or thirds, depending on what best fits the size of your slider buns. Place the hot dogs over the cheese.
- Spoon the chili over the hot dogs.
- Sprinkle the diced onion over the entire top.
- Add the rest of the shredded cheddar.
