Bring a pot of water to boil. Meanwhile, place Quinoa (1 cup) in a sieve and rinse under cold water. When water boils, add quinoa and simmer for 9 minutes. Drain in an fine-mesh sieve and run under cold water until cool. Set aside to dry.
Prepare the remaining ingredients: Slice the Sugar Snap Peas (1 cup) on a bias and set aside. Roughly chop the Cashew Nuts (1/2 cup). Slice the Scallion (5) thinly. Remove the seeds from the Serrano Chili (2), then finely dice.
Peel the Mango (2) and slice down and around the pit, then dice the flesh. Grate the Fresh Ginger (1 inch) on a box grater or finely dice with a knife. You need about a tablespoon of minced ginger flesh/juice.
Place the quinoa into a large bowl. Season with Kosher Salt (to taste) and Ground Black Pepper (to taste). Add peas, cashews, scallions, serrano chili, ginger, Extra-Virgin Olive Oil (1/3 cup), and juice of the Lime (2). Toss and taste. Adjust seasoning as necessary.
Let salad marinate in the fridge for an hour (if you have the time). Fold in the mango just before serving.
