Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Slice the jalapeño in half lengthwise, remove the seeds, and finely mince one half while slicing the other half into thin rings for garnish.
In a medium mixing bowl, combine the ground beef, minced jalapeño, sea salt, black pepper, and garlic powder, mixing gently with your hands until just incorporated.
Divide the beef mixture into two equal portions and flatten them into thick discs.
Place half of the goat cheese in the center of each disc, then carefully fold the meat around the cheese to form a sealed slider patty.
Wrap one slice of bacon tightly around each slider, securing the ends with a toothpick if needed.
Heat the olive oil in a cast-iron or oven-safe skillet over medium-high heat.
Sear the sliders for 2 minutes per side until the bacon begins to crisp and brown.
Transfer the skillet to the oven and bake for 8 to 10 minutes until the beef reaches your desired doneness and the bacon is fully cooked.
Remove the toothpicks and serve each slider inside a crisp romaine lettuce leaf, topped with the reserved jalapeño rings.
