Heat the olive oil in a large skillet or casserole (like the Viking Professional Stainless Steel Casserole). When it shimmers, add the onions, red peppers, and garlic and cook for 4-5 minutes over medium-high heat, until they begin to get a little color.
Add the chopped kale and stir to combine. Once it has wilted, add the diced chicken sausage and stir to combine. Cook until the sausage begins to brown a little and the pan seems quite dry. Add the wine/chicken stock and stir to combine.
Pour the tomatoes and their juice into the pan and stir to combine.
Add the pasta and stir it in.
Bring the sauce to a boil. Reduce the heat to medium and put a lid on the pan.
Cook for 10-12 minutes, until the pasta is cooked. Season to taste. Serve with grated parmesan cheese on top.
