Deseed the jalapeños and cut them into strips. Cut the Roma tomatoes into small wedges and slice the onion.
Wrap each hot dog with a strip of bacon. The thinner the bacon, the better.
Heat a pan over medium heat and add the bacon-wrapped hot dogs along with the veggies. Add salt to the veggies.
Cook until the veggies are softened and the hot dogs develop a nice golden color.
Spread mayonnaise on the hot dog buns and toast them in the pan over low heat until golden and crispy.
Place the hot dogs in the buns and top them with the sautéed veggies.
Enjoy!
