Preheat the oven to 425°F (220°C). Line two baking sheets with parchment for easy cleanup.
Prep the veggies. Cut the sweet potato, pepper, onion, broccoli, and zucchini into bite-size pieces.
Pat the chickpeas dry with a towel so they roast well.
Season generously. On the baking sheets, toss veggies and chickpeas with olive oil, smoked paprika, cumin, garlic powder, chili flakes (if using), salt, and pepper. Spread everything in a single layer so they roast, not steam.
Roast to caramelized perfection. Bake for 22–28 minutes, tossing halfway. You’re looking for browned edges and tender centers.
The chickpeas should be slightly crisp.
Cook the grains. While the veggies roast, prepare quinoa, rice, or farro according to package directions if you haven’t already. Fluff with a fork and season lightly with salt.
Make the dressing. Whisk tahini, lemon juice, maple syrup, and garlic. Add warm water a little at a time until the sauce is pourable.
Season with salt and pepper.
Assemble the bowls. Add a handful of greens to each bowl. Top with warm grains, a generous scoop of roasted veggies and chickpeas, avocado slices, and pumpkin seeds. Drizzle with dressing and sprinkle with fresh herbs.
Taste and adjust. Add a pinch more salt, a squeeze of lemon, or extra chili flakes if you want more brightness or heat.
