There are two ways to grill the polish sausage on the griddle. You can grill the sausage who, like we did here on Blackstone Grilled Bratwurst. You can also slice them up like we did in this recipe, for an easy to sauté them on the griddle. We prefer to slice them and then put them on the grill. This allows for every piece to get the crispy texture. We actually like them a little burnt on the edges.
