White Castle invented the slider. Then we invented the Cheese Slider. Then we kicked it up a notch. The Jalapeño Cheese Slider adds a spicy kick to that legendary 100% beef, cheese and onion combo. So if your thing is a little more zing, have we got a slider for you. These Jalapeńo Cheese Sliders are so addictive, and so easy to make, that the next time you check this box, it could be empty. From our Castle to your freezer.
