Cook the quinoa per packet instructions and then set aside to cool completely.
Cut the Peaches in half and then carefully remove the stone. This works best with ripe, but still firm peaches! Then slice the peach halves into 4-6 wedges each.
Use a vegetable peeler to cut the cucumber into thin ribbons.
Then add the halved cherry tomatoes, mixed leaves, cucumber and peaches to the quinoa. Crumble feta on top and drizzle with half juice of a lemon and 2tbsp olive oil.
