Preheat your oven to 375°F and prepare a baking sheet lined with parchment paper.
Divide the ground turkey into two equally sized patties. Gently form each patty and season with salt and pepper if desired.
Slice the jalapeño pepper in half lengthwise, removing seeds if a milder heat is preferred.
Place a few strips of jalapeño along the center of each turkey patty.
Wrap each patty with a slice of bacon around the edges, securing it with a toothpick if necessary.
Heat a nonstick skillet over medium heat and sear the bacon-wrapped patties for about 2 minutes per side until the bacon starts to crisp.
Finish cooking the patties in the preheated oven for 10-12 minutes, or until the turkey is cooked through and bacon is extra crispy.
Meanwhile, lightly toast the whole-wheat slider bun.
Assemble the slider by spreading a teaspoon of yellow mustard on the bun, placing the patty on top, and topping with the other half of the bun.
Serve immediately while hot and enjoy these protein-packed, spicy, and savory sliders.
