A method for preparation of a pizza which includes providing a crust having a peripheral edge; providing a preformed slice of cheese having (1) a substantially uniform thickness, (2) that is dimensioned and configured to extend over the crust and intermediate the peripheral edge thereof and (3) has a plurality of holes disposed therein. Thereafter, the step of positioning the preformed slice of cheese on the crust is followed by baking the crust and the preformed slice whereby gases trapped intermediate the preformed slice and the crust escape out through the holes in the preformed slice.
