re: Would like some suggestions to improve a pasta recipe..

Sausage probably didnt need any seasoning.
I wouldn't use the Moore's stuff in an alfredo.
Make sure you season your chicken and veggies with salt and pepper every step of the way.
Alfredo is an easy sauce, and most people find it very impressive if they've never made it. Definitely take the extra couple minutes to throw one together and dont use the parmesan that comes in a green can..it'll make your sauce gritty. Get the real stuff from the cheese aisle
