Lemony Avocado Pasta Sauce

A very quick, very simple, very delicious dinner. Imagine whacking guacamole on a pasta sauce and you've got the right idea. When blended, the avocado is very creamy and it -just- works. I found this recipe a while ago here, and have been meaning to cook it ever since. I modified it for my own ends (cooked the garlic rather than using it raw, and added chilli) but it's a pretty simple recipe so not much modification needed. You don't have to add cheese to this  (e.g. if you are vegan or worried about fat content)  but I love cheese so yeh that was always going to be done when I cooked this to be honest...
