I love mint, so this was a natural progression. I think pistachios are better than pinenuts with mint, and almonds work well also. You could use either one, but I like the mixture. I prefer to use a mortar and pestle for my pesto, both for flavor/texture, and because it is hard to do smaller batches in a food processor. Both methods are given , but I hope you will try the mortar and pestle method.
