Season the rib eyes with salt, pepper, and garlic.
Slowly sauté the sliced white onions, seasoning with salt, pepper, and garlic, and deglaze with some Sam Adams October Fest.
Make a beer cheese sauce by adding more Sam Adams October Fest and shredded cheese, and cook until thickened.
Cook the seasoned rib eyes until they reach an internal temperature of 120°F, then let them rest and thinly slice.
Build the sliders by layering the cheese, steak, onions, more cheese, and topping the slider rolls with butter and bagel seasoning.
Put the assembled sliders back on the smoker or grill until the tops are golden brown.
Serve the sliders with the warm beer cheese sauce on the side for dipping.
