Preheat the grill. Set your grill up for two-zone heat, meaning one side with direct heat, the other with indirect heat, and an overall temperature of 350 degrees F.
Prepare the pork. Drizzle the pork tenderloins on all sides with avocado oil, then sprinkle them evenly on all sides with the Sweet Rub.
Grill the tenderloins. Place the pork tenderloin on the center of the grill, close the lid, and cook for 4-6 minutes. The pork tenderloin should have nice grill marks and release easily from the grill. Turn the pork tenderloin ¼ turn, close the lid, and continue cooking for 4–6 minutes. Repeat this process twice more, until all four sides of the tenderloin have been grilled and the internal temperature of the pork reads 135 degrees F with an instant-read meat thermometer. The whole process should take between 15 and 20 minutes.
Glaze and grill. Once your pork tenderloin is at 135, it is time to baste with the Hot Honey BBQ Sauce. Use a basting brush to paint the sauce on all sides of the pork tenderloin, turning it on the grill as needed. Baste and rotate the pork on the grill until the internal temperature reads 145 degrees F and the sauce is caramelized and sticky on the outside of the pork.
Rest and serve. Remove the pork tenderloins to a serving platter and allow them to cool for 5-7 minutes before slicing into medallions.
Assemble the sliders. Using a large bread knife, slice the rolls in half, separating the tops from the bottoms. Set aside the tops of the rolls. Layer the pork tenderloin medallions on the bottom half of the rolls, top each roll with a few sliced of red onion, and drizzle with more of the Hot Honey BBQ Sauce. Place the other half of the rolls on top of everything, separate the rolls into individual sliders, serve, and enjoy!
