Preheat the oven to 425°F. Line a baking sheet with aluminum foil, and spray with nonstick cooking spray. Place a cooling/baking rack on top of the prepared baking sheet. Set it aside.
Add the cream cheese and kosher salt to a medium-sized mixing bowl. Use a handheld mixer at medium speed. Beat the cream cheese for 30 seconds to 1 minute until smooth.
Add the shredded cheese and mix until well combined.
Fill the halved jalapeños with the cream cheese mixture.
Place 1 sausage on top of the cream cheese layer.
Carefully wrap the stuffed jalapeño with the halved bacon slices and place it on the prepared baking sheet. Bake for 20 to 25 minutes on the second-highest oven rack. Keep a close eye on the bacon to ensure it does not burn. Remove from the oven. Allow the stuffed jalapeños to rest for 5 minutes. Serve with your favorite dipping sauce, blue cheese, or ranch dressing.
