The Internet can't decide if it loves or hates this easy way to slice a frozen pizza. The hack is that you DON'T slice it. You take the packaged frozen pie, put it on the edge of the counter halfway, and hit the outer edge so it breaks in half.
Then you rotate it, and repeat. When you get it out of the oven, it's precut. Some people who saw the clip thought it was "genius." Others weren't impressed, saying it has to be baked on a pan, because if it's cooked on the rack, the cheese will leak.
