I have made this a lot and have come up with several variations. My favorite is to add a chunk of cream cheese to make the sauce a bit thicker, to omit the potatos and serve it over couscous instead, to use green onions instead of yellow, and to add a diced red bell pepper :-) nom nom nom!!!
This was absolutely divine. Highly recommended!
I made this for me, my boyfriend and his roommate and it was an absolute HIT! Awesome, especially in the cold winter months!!
