Preheat the oven to 160°C conventional (140°C fan-forced). Place the almonds on a tray and roast for 10–15 minutes. Remove and set aside until cooled. Roughly chop. (To save time, you could simply buy roasted almonds and skip this step.)
Place a medium saucepan over medium heat. Add the water and bring to the boil. Add the quinoa and turn the heat down to a gentle simmer. Cook for 15 minutes. Drain and run under cold water. Set aside.
For the dressing: Combine all the ingredients in a bowl. Mix and season to taste.
In a large salad bowl, place the quinoa, rocket, tuna, cucumber, cherry tomatoes, red onion, parsley, avocado, goat's cheese and almonds. Season, drizzle over the dressing and gently toss.
