Begin by preheating your grill to medium high heat (about 350F) for direct cooking.
Add a cast iron skillet to the grill to preheat for 5 minutes.
Add your spicy italian sausage to the skillet to cook until fully done (about 8-10 minutes).
Once done, drain of excess fat and set to the side to cook off.
Pull your Kings Hawaiian Slider Rolls out of the packet and slice in half so theres a top and bottom.
Grease a foil sheet pan and place the bottom of the slider rolls into it.
Begin building your sliders with a layer of mozzarella cheese, marinara sauce, spicy ground sausage, more cheese, prosciutto, salami, coppa, calabrian pepper oil, more cheese, pesto sauce and the top bun.
In a bowl, mix together the butter, minced garlic and chopped parsley.
Brush the butter mixture over the top of the rolls then add grated parmesan on top.
Heat your grill to medium heat (300F) for indirect cooking.
Add the sliders to the grill on the cool side to cook for 15-20 minutes or until the sliders are golden brown.
Pull off and let cook once done.
Slice the sliders up, serve with marinara for dipping and enjoy!
