Preheat oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Prepare vegetables: cut broccoli into florets, slice sweet potato into rounds, and chop kale.
Toss broccoli with olive oil, garlic, salt, and pepper. Spread on one section of the baking sheet.
In the same bowl, mix chickpeas with oil, sriracha, and soy sauce. Spread next to broccoli.
Toss sweet potato with oil, curry powder, sriracha, and salt. Place on the remaining section of the tray.
Bake for 10 minutes, then flip vegetables and stir chickpeas. Bake another 8–12 minutes until tender.
Meanwhile, cook quinoa by combining it with vegetable broth in a pot. Bring to a boil, then simmer covered for 12–15 minutes until fluffy.
In a bowl, massage kale with oil, lime juice, chili powder, salt, and pepper until softened.
Assemble the Roasted Veggie Quinoa Bowl by adding quinoa, roasted vegetables, chickpeas, and kale.
Top with avocado, hummus, or lime if desired and serve.
