Preheat oven to 425F convection or 450F. Line a baking sheet with parchment.
Add broccoli to the baking sheet and toss with oil and salt. Bake for 10-15 minutes, or until lightly charred.
In a medium pot, add the quinoa and 1 ½ cups water. Bring to a boil, then reduce the heat and simmer, covered, for 12 minutes or until cooked through and water has evaporated. Fluff with a fork and set aside to cool off a bit.
Warm the chickpeas up in the microwave (warming up canned beans lets them absorb flavor a lot better).
Add all dressing ingredients to a high speed blender and blend until smooth. If too thick, thin out with additional water.
Toss warm quinoa with spinach and about 2 tablespoons of the pesto dressing. Top with roasted broccoli, fennel, bell peppers and chickpeas. Drizzle remaining dressing over top. Top with plenty of nuts and parmesan (if using).
