Preheat oven to 400°F (200°C). Toss the sweet potato, cauliflower and chickpeas with olive oil, smoked paprika, cumin salt, and pepper on a baking sheet.
Roast for 30 to 35 minutes, flipping halfway, until tender and slightly crispy.
In the meantime, cook couscous according to package directions. I prefer to cook it in vegetable broth instead of water, for extra flavor.
For the dressing, whisk all the ingredients in a jar until smooth.
In a large bowl, combine couscous, roasted sweet potato, cauliflower, chickpeas, herbs and pumpkin seeds.
Drizzle with the vegan pesto tahini dressing and toss to combine. Serve warm or chilled.
