Set 6 quarts of salted water to boil in a large pot.
Meanwhile, chop red pepper and slice the smoked sausage into 1/4 inch-thick rounds.
Stir-fry red pepper and sausage together until heated through -- about 5 minutes.
Add tortellini to boiling water and cook for 5 minutes.
Add edamame to water and boil for another 2 minutes. Drain tortellini and edamame well.
Toss everything together with the Italian dressing and heat through one final time. Serves 5-6.
