Bring quinoa and water to a boil in a large saucepan over medium heat. Reduce heat to low-medium and let simmer for 15 minutes, covered. Remove from heat and let sit for 5 minutes, fluff. Let cool slightly. *If your quinoa has different instructions, go with them.
Toss together cooled quinoa and remaining ingredients: cherries, rosemary, walnuts, lemon juice, shallot, and salt; drizzle honey. Toss in blue cheese at the end to prevent clumping. You may want to toss the arugula in a drizzle of olive oil if adding.
