Preheat oven to 220°C (200°C fan-forced). Line a large, rimmed baking tray with baking paper.
Mix cauliflower florets, garlic powder, smoked paprika, ground cumin, olive oil, salt and pepper in a medium bowl.
Spread cauliflower on the prepared tray and roast in the preheated oven for approximately 20 minutes until golden and tender. Remove from the oven and set aside to cool slightly.
Prepare the dressing by mixing balsamic vinegar, grain mustard, minced garlic, lemon juice and zest and olive oil in a small bowl. Mix well.
To assemble the salad, add chickpeas and cooked quinoa to a large bowl. Add spring onion, raisins, toasted almond flakes and roasted cauliflower. Top with parsley and salad dressing. Mix well to ensure the dressing coats everything evenly.
Serve in a large platter.
