Place your chuck roasts on a baking sheet, slather them with beef tallow, and generously season all sides with my Mesquite Peppercorn Lager Rub, completely covering the roasts.
Place them in the fridge, uncovered, for at least 4 hours but ideally overnight.
While the roasts are in the fridge, preheat your smoker to about 250 degrees F. Add some wood chips or wood chunks, if desired, for extra smoky flavor.
Pull your chuck roasts out and place them on the smoker to cook until reaching an internal temperature of 165 degrees F (about 3 hours).
Once the chuck roasts have hit temperature, pull them out and place them in a large foil bin. Fill the bin with beef broth, beef tallow, sliced jalapenos, and sliced yellow onions. The liquid in the bin should come up to 50% of the chuck roast’s height, so add more or less, as needed.
Tightly cover your bin with aluminum foil and place it back on the smoker at 300 degrees F to smoke until the meat is tender and shreddable (another 3-4 hours).
Once the chuck roasts are done, pull them off and let them rest for 20 minutes. After the rest, pull the chuck roasts out and shred them up.
While keeping the slider rolls together, slice the slab of bread in half so that there is a top side and bottom side.
Add the bottom side into a foil bin or other heat-safe pan. Add a layer of HNY FYR BBQ Sauce, then start building with quite a bit of pulled beef, sliced cheddar cheese, more BBQ sauce, and then the top part of the buns.
In a bowl, melt some butter. Gently spread the melted butter over the top of the rolls then top.
Get your smoker to a medium heat (around 300-325 degrees F) for indirect cooking. Add your sliders in the foil bin onto the smoker to cook until they are golden brown & crispy (about 10-12 minutes).
Once done, pull the sliders off and let cool for 2-3 minutes before serving.
Serve with more HNY FYR BBQ Sauce for dipping if desired. Enjoy!
