Penne With Black Kale, Sausage, and Roasted Peppers (or sun dried tomatoes)

1 Tbsp olive oil
3/4 lb hot italian sausage, cut into chunks
1 lb penne pasta
1 lb black kale, leaves torn into 2 inch pices, stems discarded (I tried to make this for mom and she accidently got red-leaf lettuce instead of kale - it's not quite the same)
1 (12 oz jar roasted red peppers, drained, cut into strips - I can never find this so I use sun dried tomatoes
2 cloves garlic finely chopped
1/2 cup shredded parmesean cheese

1. Bring a large pot of salted water to boil
2. Meanwhile, heat olive oil in a large, deep skillet over medium heat; add sausage. Cook until browned and halfway cooked through, about 7 minutes. At this point, add pasta to boiling water, stir a few times, and cook according to package directions
3. Add Kale to sausage; cover skillet and cook 2 minutes, tossing once or twice, or until kale is wilted. Stir in peppers (or tomatoes)and garlic; cook 7 minutes longer, or until sausage is cooked.
4. drain pasta, reserving 1/2 cup of the cooking water. Return pasta to pot; add sausage mixture and reserved cooking water, and toss. Sprinkle with parmesan cheese.
