In a pot, combine 1.5 cups quinoa with 3 cups water or bone broth. Bring to a boil. Reduce heat, cover and simmer until liquid has evaporated (about 15 minutes). Let stand 5 minutes, then fluff with a fork.
For the dressing, combine all ingredients in a jar and shake until well mixed.
Once the quinoa cools off a bit, put it in a large bowl with the bell pepper, tomatoes, green and red onions, parsley, and mint. Add the dressing a stir to combine.
Enjoy!
