Preheat oven to 400 °. Line baking sheet with tin foil or parchment paper.
Place bacon on one half of the sheet pan and sprinkle with brown sugar. On the other half place the sliced jalapenos. Bake until the bacon is crispy and the jalapenos are caramelized and soft. If the jalapenos are getting done before the bacon, remove them from the baking sheet and finish baking the bacon. Chop both the bacon and jalapeno slices and set them aside for later.
3 pieces bacon, 2 teaspoon brown sugar, 2 medium jalapenos
Peel the eggs and slice in half. Place the egg yolks, mayonnaise, mustard, red wine vinegar, sugar, a pinch of salt and pepper into a medium bowl. Using a fork or hand beaters, mash the ingredients together until the mixture until mostly smooth.

To serve, arrange bacon jalapeno eggs on a platter. Top with a jalapeno slice and/or green onion along with extra bacon pieces if desired.
