Kraft Kitchen tips:
MAKEOVER SAVINGS Save 7g of fat per serving when compared to a traditional tetrazzini by preparing this delicious version with boneless skinless chicken breasts, KRAFT 2% Milk Shredded Mozzarella Cheese, PHILADELPHIA Neufchatel Cheese and fat-free reduced-sodium chicken broth. And as a bonus, these changes will result in a savings of 30 calories per serving.
VARIATION Substitute 1-1/2 cups chopped leftover cooked turkey for the chicken, adding it to the cooked spaghetti along with the vegetables.
COOKING KNOW-HOW If you break the spaghetti in half before cooking it makes serving the dish easier.
