So, basically tuna pasta bake is one of my favourite comfort foods to make at uni. It's cheap, involves hardly any prep and is so gloriously carb-filled that it's perfect for days when I just want to slob out and chill. If you have a couple of tupperware boxes to hand, this is a brilliant recipe for creating leftovers. Personally I hate having to get up and prep my lunch before going to uni - this way, it's already ready from dinner the night (or a few!) before.
