Glad you asked...
You can cook fresh kielbasa by adding it to your spaghetti. Just peel the kielbasa, and while you are heating up your spaghetti sauce, just add your kielbasa to the pot, and let it cook until the sauce has been heated.Just make sure you chop your kielbasa into small pieces.
Then again, this answer might help you...
Cut kielbasa in five inch chunks and brown in fry pan. Place browned kielbasa in baking pan, cover with partially drained sauerkraut, and home made dumplings. Cover with foil and bake in slow oven for 1 hour.
