Preheat oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
In a large mixing bowl, whisk together olive oil, sriracha, soy sauce, honey, garlic powder, smoked paprika, salt, and pepper.
Add cauliflower florets and dried chickpeas to the bowl and toss until evenly coated with the sauce.
Spread the mixture in a single layer on the prepared baking sheet, ensuring no overcrowding.
Roast for 25 to 30 minutes, tossing halfway through, until cauliflower is tender and chickpeas are slightly crispy.
Remove from oven and serve immediately, optionally garnished with fresh cilantro or green onions.
