Rosemary Pasta with Chicken

I made this with my brother the night of the big storm a week or two ago. He made the rosemary chicken - marinated in olive oil, rosemary, garlic, salt, pepper and lemon - grilled on the stove top in our grill pan.
I made the pasta - after the chicken was done, I added butter to the pan and tossed in some chopped onion and garlic. Once the onions were soft, I added some white wine to deglaze the pan. Then I added some chicken stock, cream, more rosemary, thyme, hot pepper flakes and kale. You've got to be patient and let the sauce thicken, or you can toss in some cornstarch if you're lazy (take some sauce from the pan and mix the cornstarch in - then add to the pan).
It was a last minute easy throw together pasta dish that was quite tasty. The rosemary gave it a different flavour than my usual pasta!
