Cut each of the cheese sticks in half and place them in the freezer until frozen solid.
Preheat your grill to 400°F and prepare for indirect grilling.
Place flour into a shallow bowl.
In another shallow bowl, beat the egg.
In a last shallow dish, place the breadcrumbs, bone dust and parmesan cheese. Combine well.
Coat the Stainless Steel Griddle with the oil.
Take each piece of cheese string and individually coat in flour, followed by the egg, and then the crumbs. Re-dip the coated cheese in the egg wash and again into the crumb mixture.
Repeat this process with all of the cheese sticks, then place the griddle over the “off” side of the grill.
Let the Mozzarella Sticks grill bake for two to three minutes, letting the bottoms become crisp. Then flip them so that the other side can do the same, allowing them to grill bake until golden and gooey. Watch them in the last minute or so, you don’t want them to start oooozing.
Serve immediately with spicy marinara or salsa.
