Preheat your oven to 400°F. Slice the sweet potato into four 1/2-inch thick rounds and toss with avocado oil, sea salt, and black pepper.
Place the sweet potato rounds on a parchment-lined baking sheet and roast for 20 minutes, flipping halfway through, until tender and lightly browned.
While the potatoes roast, finely dice the jalapeño, removing the seeds if you prefer less heat, and mix it with the shredded cheddar cheese.
In a small bowl, season the ground turkey with garlic powder and onion powder, then divide the mixture into two equal portions.
Flatten each turkey portion into a disc, place the jalapeño-cheese mixture in the center, and fold the meat around it to form a sealed patty.
Wrap one slice of bacon tightly around each turkey patty, securing the ends with a toothpick to keep it in place during cooking.
Heat a non-stick skillet over medium heat and sear the sliders for 5-6 minutes per side until the bacon is crispy and the turkey is cooked through.
Remove the toothpicks and place each slider between two roasted sweet potato rounds to serve as the bun.
