Cook the Quinoa Base: In a medium saucepan, combine rinsed quinoa and water. Bring to a boil over medium-high heat. Once boiling, reduce the heat to low, cover, and simmer for 15 minutes. Remove from heat and let the quinoa sit, covered, for an additional 10 minutes. Fluff with a fork before serving.
Blend the Green Pesto Sauce: In a high-speed blender, combine the pepitas (or pistachios), garlic, kale, cilantro, lemon juice, salt, pepper, olive oil, water, and maple syrup or honey. Blend until smooth and creamy. Adjust seasoning to taste if desired. Set aside.
Roast the Vegetables: Preheat your oven to 425°F (220°C). Line two baking sheets with parchment paper. Spread the chopped parsnips, Brussels sprouts, and cauliflower on one tray, and the broccolini on the other. Drizzle with olive oil, season with salt and pepper, and toss until evenly coated. Roast the first tray for 20–25 minutes or until the vegetables are golden and caramelized around the edges. Roast the broccolini for 10–12 minutes, or until tender. Once cool enough to handle, chop the broccolini into bite-sized pieces.
Assemble the Bowls: To each bowl, add a generous scoop (about ½ cup) of cooked quinoa. Top with a mix of roasted vegetables, ¼ cup chickpeas, and a spoonful of sauerkraut. Drizzle with the creamy pesto and sprinkle toasted pepitas on top. Finish with fresh cilantro and additional salt and pepper, if needed.
