Preheat oven to 400 degrees f. and line a baking sheet with parchment paper.
In a mixing bowl, toss the Brussels sprouts, bell pepper, oil, garlic, salt and pepper.
Transfer to the baking sheet and bake for 20-25 minutes, or until golden brown and tender.
In a pot, combine quinoa and vegetable broth. Bring to a boil and reduce heat to simmer for 12-15 minutes, until quinoa is fluffy.
In a small bowl, whisk together all of the dressing ingredients. Set aside.
In a large serving bowl, combine cooked quinoa, roasted Brussels sprouts and peppers.
Then gently toss with the dressing until well combined.
Garnish, serve and enjoy!
