Heat Blackstone to Medium-high. My two burner, I set left to Medium High, right to low to keep warm
Throw a pad of butter or some oil and brown the kielbasa slices. When they're nice and cooked, push to the warm side of the Blackstone, or remove.
Add onion and cook until translucent. Add garlic at the end for 1-2 minutes and cook until fragrant.
Add the kraut and combine with onion. Cook until the mix is a golden brown.
Re-introduce the kielbasa to the blend and keep on warm side. Throw another pad of butter down and cook frozen pierogi per instruction.
Enjoy
