Place the rinsed quinoa in a medium sized pot and add 1 3/4 cups water. Bring to a boil and reduce the heat to low. Simmer the quinoa for 13 minutes. Turn off the heat, fluff the quinoa with a fork, and let it sit for 5 minutes. The quinoa can be prepared up to two days in advance of making the salad and stored in an airtight container in the fridge.
Add the chopped vegetables, black beans, and herbs to the quinoa.
Whisk the dressing ingredients together. Add the dressing to the quinoa, beans, and vegetables. Toss to combine. Taste the salad and adjust salt and pepper as needed. Serve or store. Leftovers will keep in an airtight container in the fridge for up to four days.
