You can cut chicken breast into bite-size pieces and cook first in oil, then saute the vegetables. Add the cooked chicken along with pasta to the sauce. Shrimp or Italian sausage can be used as well!
I prefer a bite-size pasta for this dish but fettuccine or linguine works too!
To make toasted bread crumbs topping: melt 1 tablespoon of butter in a pan (use the same pan you will cook the dish in), add ½ cup of bread crumbs (plain or Italian style) and ¼ cup of Parmesan cheese and toast, stirring often, until nicely golden brown.
