If your grill has more than one burner, only light a couple burners on LOW heat. (Our grill has 5 burners, we used 2.)
Separate the halves of your english muffins and toast them gently on the grill open side up by placing them directly on the grill rack. (Do not leave them unattended.)
Once slightly hardened and toasty, remove from heat immediately; baste with marinara or pizza sauce.
Place favorite toppings and seasoning on top, finishing with mozzarella cheese.
Spray your metal cookie sheet or tin foil, and lay onto the grill.
Place your finished pizzas onto the foil/cookie sheet.
Close the grill lid and let cook for a couple minutes until cheese is melty, but don't overdo it. (Stay close by)
Once cheese is melted, take off the grill, placing onto a platter, and serve immediately.
