I mean the whole burger, not just the slab of mystery meat.
Textured soy meal congealed with pink slime does not a burger make. I don’t think any of the major fast food chains have actual ground beef anymore. They’ll make slippery claims that it’s beef, which rules out goat or roadkill I suppose, but it’s rendered not ground chuck and there’s a lot of filler in there, which is soy.
