Start by wrapping your bacon around each wiener, securing each end with a toothpick

In a medium-sized skillet, heat up a teaspoon or so of vegetable oil. Working in batches of four, add in the wieners and cook for about 10 minutes, occasionally turning so all of the bacon is cooked evenly. Transfer them to a plate as they finish.

After the hot dogs cook, use the same skillet to heat up a tablespoon of vegetable oil. Add in the onion and jalapeno with a pinch of salt and pepper. Stir occasionally and cook for about 6-7 minutes, or until the onions have caramelized a little bit

To assemble:

Schmear mayo on both sides of the hot dog bun, then add a weiner and top with the onion jalapeño mixture and the condiments of your choice.
