Italian Sausauge pasta dish

Tonight is Pasta night. One of my favorite quickie dinners is this simple pasta dish.
1lb Turkey or regular Italian sausage
1 sm onion
1 bell pepper
1 lg can diced tomato (drained)
1 can sliced or whole olives
1tbl basil or Italian seasoning
salt and pepper to taste
5 tbs butter, margarine or PARKAY fat free butter spray
Brown the sausage, onion and pepper. Once sausage is browned and veg are soft add tomatoes, olives, seasoning and butter. Mix well and allow enough time for the flavors to mix. Put on top of your favorite cooked pasta. I use linguine.
