I have a Grandson graduation party coming up and plan on grill some 12 inch burgers as one of the mains. Plan is to use a 12 inch quiche pan 1 inch deep with removable bottom to form and grill on first side. Flip with pizza paddle, remove quiche mold, slide pizza paddle between removable bottom and burger to grill 2nd side. Place burger with fixings on 12 round sourdough bread and cut into sections. Any thoughts or suggestions?
