Kielbasa Tortellini Alfredo

Yet another kielbasa recipe (found in a magazine). I'm just hoping there are other kielbasa lovers out there too :)

1 package (9-14 oz.) frozen cheese or spinach tortellini
1 lb. kielbasa or sausage, sliced
1 med sweet red pepper, julienned
2 tsp. veg. oil
1 jar (16 oz.) Alfredo sauce
1 cup chopped tomato (optional)

Cook tortellini according to package directions. Meanwhile, in large skillet, saute kielbasa and pepper in oil for 3 minutes or until pepper is crisp tender. Drain tortellini. Stir tortellini and Alfredo sauce into skillet; heat through. Garnish with tomato.
