You'll need a very large bowl to mix this all in, and the only way to do it is with your hands, so wash your hands and prepare to go to work. (I'm serious: just be sure to wash your hands and prepare to get dirty. It’s the only way this works. Don't be a wus!) Add all the non-liquid components into the bowl and then slowly add the liquids, until all the bread has absorbed it. You want the stuffing to be sort of slushy. And that's it!
