Before you start cooking, place your blender glass in the freezer for 15 minutes. The cold temperature of the container will keep your pesto bright and green.
Rinse mint leaves, Italian zucchini and lemons. Chop the zucchini, squeeze the lemons and zest one of them. Set aside.
Grate the cheese mix and add to it a pinch of salt. Set aside.
Take the blender out of the freezer and pour in the zucchini, the mint, the almonds, the lemon juice and the lemon zest. Start pureeing, and with the machine going add slowly the extra-virgin olive oil.
Stir in the cheese mix.
Remove from blender and set aside.
