Combine quinoa and 2 1/4 cups water in a medium saucepan and bring to a boil. Lower heat, cover the pan and simmer until quinoa is tender and a white "tail" appears around each grain, about 15 minutes. Remove from heat and let sit, covered, 5 minutes. Transfer to a medium bowl and cool.
In a large bowl, whisk together lemon juice, lime juice, honey, garlic, salt and pepper. Add quinoa, cucumber, onion and mint, and toss to combine.
I suggest preparing the salad ahead of time to allow the flavors to blend.
Add a few slices of avocado
Lemon and mint to taste, maybe a little less depending on your taste buds
