Really good pasta. Very tasty but not overwhelming. The recipe instructions are a bit confusing in that it uses a lot of the same ingredients for both the chicken and the pasta. You'll need them for both.
PERSONAL REMINDERS: Used rigattoni pasta, maybe next time use something less heavy/big, although it did a good job picking up the sauce. I also browned the sausage before adding to pot; it added a bit more flavor. I used chicken broth instead of water (mostly); may need to add more water since a lot evaporated before pasta cooked. Pasta should be a bit undercooked before adding chicken and veggies; it'll have a few more minutes to cook when stirring in everything. I added the pepper flakes only once; spicyness was nicely balanced.
