Prepare the quinoa: In a medium saucepan combine the quinoa, water and 1/4 t. salt. Bring to a boil, reduce heat to low, cover and simmer until the liquid is just absorbed, about 15 minutes. Spread the cooked quinoa out on a baking sheet to cool for about 20 minutes.
In a large bowl whisk together lime juice, zest, honey, sour cream and olive oil. Add the cooled quinoa, strawberries, mango, cucumber and mint. Toss well to combine and season with salt & pepper. Serve immediately.
