01 - Rinse quinoa thoroughly under cold water until water runs clear. Combine quinoa, water, and salt in a saucepan. Bring to a boil over high heat, then reduce heat to low, cover tightly, and simmer for 15 minutes until liquid is absorbed. Remove from heat and fluff with a fork. Allow to cool completely before assembling salad.
02 - Preheat grill or grill pan over medium-high heat. Lightly brush mango slices with olive oil. Grill for 2 to 3 minutes per side until distinct grill marks develop and fruit is lightly caramelized. Transfer to a cutting board, let cool briefly, then cut into bite-sized pieces.
03 - In a large mixing bowl, add cooled quinoa, grilled mango pieces, diced red bell pepper, chopped red onion, halved cherry tomatoes, diced cucumber, cubed avocado, and fresh cilantro. Toss gently to distribute ingredients evenly.
04 - In a small bowl, whisk together extra virgin olive oil, fresh lime juice and lime zest, maple syrup (or honey), minced red chili, minced garlic, ground cumin, salt, and black pepper. Whisk vigorously until emulsified and fully combined.
05 - Pour chili-lime dressing over the salad mixture. Toss gently to coat all ingredients without mashing the avocado. Taste and adjust seasoning with additional salt or pepper if needed. Serve immediately, or refrigerate for 30 minutes to allow flavors to meld together.
