Preheat the oven to 400°F (200°C). Line a large baking sheet with parchment paper.
Rinse the quinoa under cold water. In a medium saucepan, combine the quinoa and water. Bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until the liquid is absorbed. Fluff with a fork and let cool.
Drain, rinse, and thoroughly dry the chickpeas. Chop the red bell peppers and red onion into 1-inch pieces.
Spread the chickpeas, red bell peppers, and red onion onto the prepared baking sheet. Drizzle with 1 tablespoon of olive oil, and sprinkle with half of the salt and black pepper. Toss to coat evenly.
Roast in the preheated oven for 25-30 minutes, or until the chickpeas are crispy and the vegetables are tender with slightly charred edges.
In a small bowl, whisk together the remaining 2 tablespoons of olive oil, lemon juice, minced garlic, and the remaining salt and black pepper to create the dressing.
In a large serving bowl, combine the cooled quinoa, roasted chickpeas, roasted red bell peppers, roasted red onions, freshly chopped dill, and parsley.
Pour the dressing over the salad and toss well to combine. Serve immediately or divide into airtight containers for meal prep.
