For a more intense jalapeño flavor, consider adding a pinch of jalapeño powder to the meat mixture. Brioche buns add a touch of richness and sweetness that complements the spiciness of the sliders. Feel free to customize the spicy ranch dressing to your liking by adding more or less salsa. These sliders can also be cooked in a skillet on the stovetop. Use medium heat and cook for the same amount of time, flipping halfway through. Consider adding a slice of pepper jack cheese to each slider during the last minute of grilling for an extra layer of flavor and spice.
