Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a mixing bowl, toss the broccoli florets with the extra virgin olive oil, sea salt, and garlic powder until every piece is evenly coated.
Spread the seasoned broccoli across the baking sheet in a single layer and roast for 15 to 20 minutes, or until the edges are tender and slightly charred.
While the broccoli is roasting, heat a non-stick skillet over medium-low heat and add the liquid egg whites.
Cook the egg whites, stirring gently and constantly with a spatula, until they are fluffy, opaque, and fully set.
In a small ramekin, whisk the tahini with a teaspoon of warm water until it reaches a smooth, pourable consistency.
Assemble the bowl by placing the cooked quinoa at the base, then layering on the roasted broccoli and scrambled egg whites.
Garnish the bowl with the hemp hearts and drizzle the velvety tahini dressing over the top before serving immediately.
