In a large bowl, gently mix all the ingredients except 1/4 cup of breadcrumbs. Try not to squeeze it through your fingers, as fun as that is it may affect the end texture. When it's mixed, cover the bowl and place it in the fridge for at least an hour, preferably a day.
Preheat the oven to 400 degrees F.
Line a baking sheet with parchment paper and scoop out a ping pong sized ball of meat and place on the paper, roughly shaped into a ball. Roll the ball lightly between your palms to form the ball shape. When the balls are shaped, place them one at a time in a small bowl of 1/4 cup of breadcrumbs and shuffle the ball around to give it an even crust of crumbs.
If you have a mini muffing tin, try cooking one ball in each muffin cup to help the balls keep their shape. If not, just use a baking sheet.
