Italian Shrimp & Pasta

We haven't been grocery shopping in a long time (think before Thanksgiving), and we are trying to use what we have in our freezer/cabinet/fridge. We dug some shrimp out of the freezer and went to google to figure out what to do with it.
We picked this recipe and stuck mostly to it -- we added some crushed red pepper flakes for some spice and some tomato paste to thicken it up based off of the comments that said it was watery.
It turned out great, and the added spice was a nice touch.
