1) Bring 2 cups water and quinoa to a boil in a small saucepan. Cover, reduce heat, and simmer for 15 minutes; fluff with a fork and allow to cool.
2) Whisk the vinegar, oil, honey, salt and pepper together in a bowl, stirring with a whisk until the honey dissolves. Try microwaving the mixture for 10 seconds if the honey isn't dissolving easily.
3) Just prior to serving, toss quinoa, peaches, nuts, mint, and dressing together. Enjoy!
