Fit two pizzas in one pan
Does it not simply frustrate you to have to use a giant pan to cook each pizza in because no matter how much wrangling you do, they just will not fit in a single one? The worst part is that there is always plenty of free space, but the round shape is simply awkward and inefficient. Luckily, there is something you can try.
Keeping the pizzas in their original round form means that there is a ton of free space that is wasted. If you pre-cut the slices, then you can use up the space better and fit many more pieces in a single pan. That way, you can avoid any extra clean-up when it is time to wash the dishes.
