Bring a pot of water to boil. Meanwhile, place the Quinoa (1 cup) in a sieve and rinse under cold water. When water boils, add the quinoa and simmer for 9 minutes. Drain in sieve and run under cold water until cool. Set aside to dry.
Slice up the Radish (10) into thin disks. Stack the circles on top of each other and slice straight down to get mini matchsticks.
Meanwhile, cook the edamame. Bring a tea kettle of water to a boil. Place Edamame (1 cup) in a bowl. Cover with boiling water. Let stand for 2 to 3 minutes. Drain. Rinse under cold water until cool. Set aside.
Place the cooked quinoa into a large bowl. Season with Kosher Salt (to taste) and Ground Black Pepper (to taste). Season with Crushed Red Pepper Flakes (to taste) over top if you are using.
Add the edamame, Walnut (1 cup), Red Onion (1), Scallion (5), radishes, Extra-Virgin Olive Oil (1/3 cup) and the juice of the Lemon (1) to the bowl. Toss and taste. Adjust seasoning as necessary. Enjoy!
