Cook tortellini according to package directions. Drain and run through cool water, until cooled.
Chop the tomatoes, bell pepper, cucumber and onion on a cutting board. Then combine them with the tortellini, olives and salami in a large bowl. Pour the dressing over the top and stir gently until evenly coated.
Store in the refrigerator until ready to serve. Top with shredded parmesan cheese and chopped parsley, before serving, if desired. Serve while chilled.
Chill before serving:I like to refrigerate the salad for about an hour before serving. To serve as a meal: This dish can also be served as a main dish. If served as a main dish, it will serve 4-6.Substitutions: You can also use ziti or rotini noodles in place of the tortellini and add grilled chicken or pepperoni in place of the salami.
