Preheat the oven to 375°F (190°C). Line a large baking sheet with parchment paper and place the pork belly slices on top.
In a small bowl, mix together the salt, pepper, garlic powder, and paprika. Sprinkle the spice mixture over both sides of the pork belly slices.
Bake the pork belly for 1 hour, then remove from the oven and cover with aluminum foil. Return to the oven and bake for an additional hour, or until the pork belly is tender and crispy.
In a large frying pan, heat the vegetable oil over medium-high heat. Add the pork belly slices and cook for 2-3 minutes on each side, until crispy. Remove from heat and set aside.
In a small saucepan, combine the mayonnaise, apple cider vinegar, honey, salt, and pepper. Cook over low heat for 2-3 minutes, stirring occasionally, until the dressing is smooth.
In a mixing bowl, combine the sliced peach, diced jalapeno, chopped cilantro, and red onion. Pour the dressing over the slaw and mix well.
Slice the slider buns in half and toast them on a grill or grill pan. Place a piece of crispy pork belly on the bottom half of each bun, then top with a spoonful of the peach and jalapeno slaw. Place the top half of the bun on top.
Serve the sliders immediately and enjoy!
