In a large bowl, combine the ground beef with all of the burger ingredients except the cheese. Form the meat mixture into 12 small slider patties and place them on a tray. Refrigerate for at least 20 minutes.
Preheat the grill. Add the slider patties to the hot grill. Close the lid, and cook about 4 minutes on each side (or until desired doneness). Add slices of cheddar cheese at the end of the cooking time.
ASSEMBLE SLIDERS:
Place a burger slider on the bottom half of a slider bun. Top with bacon, jalapeños and a drizzle of barbecue sauce. Place 2nd bun on top, and serve immediately.
