Per the last comment, I added more stock (a whole 32floz. box) and omitted the wine. Added closer to 3½ cups dried noodles (rotini) instead of just 3 cups. Added a splash of worcestershire sauce and topped my bowl with some nutritional yeast (I need the b12)
I would definitely recommend adding more liquid than it calls for.
Even my mushroom hating husband took seconds (and by toddler took 3rds!)
