Preheat your oven to 425°F (220°C). Spread the cubed sweet potatoes on a baking sheet, drizzle with 1 tablespoon of olive oil, and season with salt and pepper. Toss to coat evenly, then roast for about 25-30 minutes until tender and caramelized around the edges.
Meanwhile, rinse the quinoa under cold water until the water runs clear. Place it in a small saucepan with 2 cups of water, bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes until fluffy and the water is absorbed.
While the quinoa is cooking, massage the torn kale with a teaspoon of olive oil and a pinch of salt. Spread the kale on another baking sheet and bake in the oven alongside the sweet potatoes for about 10-12 minutes, until slightly crispy and fragrant.
Once the sweet potatoes are tender and caramelized, remove them from the oven and let them cool slightly.
Fluff the cooked quinoa with a fork, then transfer it to a large mixing bowl. Add the roasted sweet potatoes and baked kale, tossing gently to combine all the flavors and textures.
Serve the vibrant mixture warm, garnished with additional seasonings or a squeeze of lemon if desired. Enjoy the contrasting textures of soft, crispy, and crunchy in every bite.
