Preheat your oven to 425°F (220°C, or gas mark 7). Lightly grease two large, nonstick baking sheets.
Add your sweet potato and chickpeas to one large baking sheet and your broccoli florets to the other. Drizzle both pans with oil, sprinkle salt over the top and toss each with your hands. Spread the sweet potatoes and chickpeas out evenly across their baking sheet, and spread the broccoli evenly across the other.
Place the sheets in the oven and bake for 15 minutes. After 15 minutes, remove from the oven and stir the veggies around, flipping over most of the sweet potato pieces. Return the pans to the oven and roast for 5 to 10 minutes, until the sweet potato and broccoli are tender.
While the veggies are roasting, make the peanut sauce. Add the toasted sesame oil, peanut butter, sriracha, ginger, maple syrup, soy sauce and vinegar to a bowl. Whisk until combined. Taste and season as you see fit.
After you remove the vegetables and chickpeas from the oven, pour the peanut sauce over the top and mix everything together. Divide the veggies and chickpeas among four bowls and serve over rice. Top with spring onions, cilantro and peanuts.
