01 - Combine rinsed quinoa and water in a medium saucepan. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes, or until water is fully absorbed. Remove from heat, fluff with a fork, and allow to cool.
02 - In a small bowl, whisk together olive oil, lime juice, maple syrup (or honey), salt, black pepper, and chili flakes (if using).
03 - In a large bowl, combine the cooled quinoa with diced mango, pineapple, avocado, chopped bell pepper, diced cucumber, finely chopped red onion, and fresh cilantro.
04 - Pour the prepared dressing over the assembled ingredients and gently toss to ensure everything is evenly coated.
05 - Optionally, top the bowl with toasted coconut flakes.
06 - Serve immediately, or chill for 30 minutes to allow flavors to meld.
