Heat the oven to 425˚F with the rack in the middle.
Grab a large bowl, and combine the pork, mushrooms, herbs, and egg white (if you’re using it). Add in the ginger, lemon zest, salt, and pepper. Mix well with your hands but don’t overwork the meat.
Divide the meat into 1½ tablespoon portions and roll into balls. Place the meatballs on a parchment-lined rimmed baking sheet and make sure they are evenly separated.
Bake the meatballs in the oven for 12-15 minutes or until cooked through. Top with freshly chopped herbs and dig in!
