1. Heat a large skillet over medium heat and add oil to the pan. Once the oil is hot, add the sausages to the pan and cook until they are browned and cooked through.

2. Meanwhile, prepare the buns by lightly toasting them in a toaster or on a griddle.

3. Once the sausages are cooked, remove them from the pan and cut into slices.

4. In a small bowl, mix together ketchup, relish, onions, mustard, water (optional), salt (optional), pepper (optional), and herbs (optional).

5. To assemble the hot dogs, place two sausage slices in each bun and top with the ketchup mixture.

6. Enjoy!
