Pasta with sausage and peas

I know I've had delicious pastas before that featured crumbled sausage and peas.  I had some chicken (uh, jalapeno chicken actually) sausages in the fridge, and my roommate had some cream and frozen peas that looked stealable.  This could've gone horribly wrong, but actually turned into a pretty tasty Scavenged Dinner.
I sliced up the sausage (it had no casing, and is pre cooked or something so I couldn't crumble it) and set it aside.
I heated two minced garlic cloves in some olive oil til fragrant, then added the sausage.  Once I felt like things were probably pretty close to heated through, I added the frozen peas, the last of my 1% milk, some cream, salt and pepper, and 1 tbsp or so of butter.  I wanted to add lots of romano or parmesan, but only had like, 2 tbsp, boo.  I let it thicken up and added a little bit of the pasta water to make it nice and saucy.  :)
It actually turned out really well - the sauce was super flavorful and I will totally make it again.

Here is a really close recipe, though I did not use anywhere NEAR the amount of cream or butter it calls for!
