Cook the pasta in salted water according to package directions.
While the pasta is cooking, grill the chicken sausage links over medium-high heat for 6 minutes. You can also pan fry the sausage. Add 1 tablespoon of olive oil or vegetable oil to skillet. Place sausages in skillet and heat on medium high about 7-9 minutes, turning frequently. If you are really in a rush, you can also lay sausage on microwave safe plate, cover with a paper towel and microwave on high for 30 seconds.
While pasta and sausage is cooking, slice the tomatoes and basil and mozzarella if not in small balls. Once the sausage is done cooking, slice the sausage into 1/2 inch chunks.
Once pasta is done cooking, toss with 1/4 cup of the balsamic dressing and let cool for 5 to 10 minutes. Add the remaining dressing, tomatoes, mozzarella, sausage, and basil. Toss well and serve warm or refrigerate for 4 hours or overnight before serving.
