As a student myself, I know how important great snacks are to revision. You need them a) for motivation, and b) to concentrate properly. I often go over-the-top and create elaborate snacks just to procrastinate even more, but these nachos are really quick and simple to make. They taste incredible too, which is another bonus.
I've made a quick guacamole too. I know that classic guacamole is made with lime, fresh herbs, red onion and occasionally chilli, but I wanted to give you a recipe that can be made with simple ingredients that you're likely to have in the cupboard (we are students after all!). Make a traditional one if you have the ingredients or the time.
