There's a few things you need to do to get the PERFECT SLICE.
put ur oven at 500 F , and put the rack second up from lowest point.
AFTER the oven has preheated (5-10min) add ur slice directly on the rack, or a steel mesh on a pan. it might work on a slightly oiled pan if that's all you got but might not get the crust toasty enough. Toast it for 3mins. depending on your oven (they're all different) u might need to toast it a bit less or longer. If you really want it crispy w char, u might toast it for 4min. But imo, 3min is seriously the perfect time.
ADD SAUCES. find the best sauces, and add em after it's done toasting. I personally like a dash of red pepper flakes.
IF you're going to use a microwave (if it's literally the LAST thing you have) mist the top of the pizza lightly w water in a spray bottle. usually the pizza should be done in 1-2min on high, some microwaves have a pizza button, use that. but watch the times, and learn the exact time that the pizza is at the perfect temp, but not too long as the cheese will melt and run everywhere and burn, which is NOT the perfect slice. Once u find the perfect time, write it down on a note n stick it on the side of the microwave, NEVER to forget.
