Earlier quoted context omitted.
If I'm working the burger station and I'm cooking an impossible burger at the same station as regular burger patties there will be transfers between one and the other, no? I didn't mean they were _literally_ cooking them in animal grease but rather figuratively.
OK, I can understand that's not the point you were making. I thought you were saying that because at many fast food places they are literally cooking them in animal grease. Many fast food places (McDonald's, Wendy's) use a flat surface similar to this: https://upload.wikimedia.org/wikipedia/commons/c/cc/Flickr_X... Typical ground beef is 20% fat (80% lean), and if you cook it on that, the fat will melt, it will hang…
They are fairly large and probably expensive, so a separate broiler may not be an option.
