I guess we mix all the ingredients together in a bowl, and then just stuff the thing.
How else do we even get close to the picture which shows all the ingredients together, but it doesn't look like it's been mixed beforehand.
That picture has to be false advertising.
Maybe they added bits of each ingredient at a time so it's a little mixed. Then just prettied up the top.
Seems like a lot of unnecessary moves for a burrito.
