Prepare the pickled red onions: finely slice the onion. Place it in a bowl with the lime juice, apple cider vinegar, and a pinch of salt. Mix and let sit for at least 20 minutes.
Make the creamy cashew-lime sauce: blend the soaked cashews with lime juice, garlic, olive oil, water, salt, and pepper. Blend until perfectly smooth and creamy, adding a little more water if needed. Set aside.
Cook the quinoa: rinse the quinoa, then cook it in twice its volume of salted water (12–15 minutes). Drain if needed, stir in the lime zest and juice, then let rest, covered, for 5 minutes.
Crisp the chickpeas and corn: toss the chickpeas with olive oil, smoked paprika (or cumin), and a pinch of salt. Heat a large pan over medium heat, add the seasoned chickpeas, and sauté for 4–5 minutes. Push them to one side of the pan and add the corn kernels to the other side. Cook for another 4–5 minutes until everything is golden and slightly crispy. Set aside.
Prepare the greens: finely slice the red (or white) cabbage. Mix it with the rocket and, if desired, a splash of lime juice. Set aside.
Get the toppings ready: rinse the sprouts, roughly chop the nuts, lightly toast the seeds in a dry pan if not already toasted, and chop the coriander.
Assemble the bowls: divide the warm quinoa between two bowls. Arrange the crispy chickpeas and corn, the cabbage-rocket mix, the sprouts, the nuts and seeds, the pickled onions, and a few coriander leaves. Drizzle with the creamy cashew-lime sauce.
