One of the nice things about this recipe is that it is easy to make and seems quite a simple dish, but actually it's very satisfying. You have to cut the potatoes up into small sticks like chips so that they cook at the same time as the pasta, then you throw in the green beans, mix in the pesto and that's it but for a sprinkle of parmesan.
I made up the pesto full quantities but used less of the pasta, potatoes and green beans as there were only 3 of us, but Tristan had the pesto on some macaroni the following night and there's a little bit left for me for lunch today. Considering how cheap it was to make anyway, it has done us well over the past few days. Definitely a recipe to return to.
