Schaller & Weber’s Polish Kielbasa comes precooked, but the flavor intensifies when it’s grilled or heated. All you have to do is slice it and serve it to enjoy this timeless European favorite. The roots of each kielbasa style stretch back to the original from Poland. So, when Schaller & Weber began making a ring Kielbasa, they looked to the originators for inspiration. In traditional style, theirs is stuffed with coarsely ground sausage, packed with garlic flavor and finished with just the right spices.
