In a saucepan, bring the water to a boil. Add quinoa and a pinch of salt. Reduce heat to low, cover and simmer for 15 minutes. Allow to cool to room temperature then fluff with a fork.
Meanwhile, in a large bowl, combine olive oil, sea salt, lemon juice, tomatoes, cucumber, spring onions, carrot and parsley.
Stir in cooled quinoa and mix well.
This recipe is delish as it's written, but to boost flavour even more you can add one or any of the following in step 2: 1/2 teaspoon lemon zest, 2 tablespoons torn fresh mint leaves, 1/2 teaspoon ground cumin.
