Preheat oven to 425 F. Line a baking sheet with parchment paper, and add peppers, onion, and chickpeas. Drizzle with olive oil and sprinkle with salt and pepper, and bake for 25-30 minutes or until chickpeas are crispy and peppers have just begun to char.
Prepare dressing by whisking together ingredients in a small bowl.
Add the quinoa, peppers, onions, chickpeas, feta, and dill to a large bowl. Toss with the dressing, and serve warm or cold with an extra sprinkle of feta and dill on top!
