Tear up the Kale in small bite sized pieces and place into a large bowl.
Add the lemon juice, oil and salt and massage for about 5-10 minutes or until kale begins to slightly wilt. Add the tomatoes and set aside.
Prick the sausage links with a fork and sauté until all the sides are nicely browned about 7-10 minutes. Transfer to a plate and slice the sausage links into rounds. If the sausage isn't fully cooked put it back in the pan after slicing it and cook until the slices are slightly crispy around the edges.
Toss with the greens and add the shaved Grana Padano on top.
