Cauliflower, pasta and cheese bake

Easy one dish meal is great ^^, esp. when I can't find enough space, haha.
I think macaroni and cheese is one of the most comfort food in the world, creamy white sauce with soft pasta, nothing can be better. But for this time we add goodness into this comfort dish. By pureeing the cauliflower, it adds creaminess without a lot of calories. When eating, cooked cauliflower cut down the richness into right amount (and if you talk about health, it provides you more fiber too). 
Because I don't have Macaroni at hand, (well, I can't find it and don't want to go out to buy it), I use spaghetti instead, actually you can use any kinds of pasta too. 
I love the creaminess of this dish, but I found out that it goes very, very well with spicy Sriracha sauce, and I ended up eating it with Sriracha sauce ^^ instead of adding more salt and pepper.
