Heat a large pot on medium with olive oil. Slice onion in half to root then thinly slice it. Put in pot with small amount of water. Cover while cooking.
Slice Sausage and toss that in with the onion.
Rinse kale and pull leaves off of the tough stem. Onion and sausage should be cooking good by now. Put all the kale on top of the sausage and onion. Sprinkle salt and red pepper. Cover again. Cook until kale is cooked through to taste. yummy
