In a large bowl combine the minced beef, pork, onion, garlic, breadcrumbs, egg, Parmesan, parsley, salt, and pepper.
Mix well until evenly combined, then roll into 12 small meatballs of equal size.
AT THE GRILL:
Prepare the barbecue for direct heat, approx. 180-230°C. If using a charcoal barbecue, you need ½ chimney starter of lit briquettes.
Heat a Slate Grill, or griddle over medium-high heat, brushing lightly with oil.
Cook the meatballs for about 8–10 minutes, turning occasionally, until browned on all sides and cooked through.
Keep warm while you prepare the other elements.
Place a small pan on the griddle and melt the butter in it.
Add the double cream and warm through, then crumble in the Gorgonzola.
Stir until the cheese melts into a smooth, velvety sauce.
Finish with a pinch of black pepper.
Keeping all 12 buns attached as one piece, slice horizontally through the centre to create a large “sandwich” layer.
Place the base section on the griddle and toast 2–3 minutes until lightly golden.
Assemble the Sliders:
Spoon a little Gorgonzola cream over the toasted base, then arrange the warm meatballs evenly across it (two per portion).
Drizzle with a little more Gorgonzola cream, scatter a few rocket leaves over the top, and place the top half of the buns back on.
Brush the tops with melted butter you can use the large Basting Dome to steam the bus slightly.
To Serve:
Serve warm with extra Gorgonzola cream on the side for dipping.
Soft brioche, rich cheese, peppery rocket, and juicy Italian meatballs make this a comforting, crowd-pleasing dish.
