Cook the grain: Prepare quinoa or brown rice according to package instructions. Fluff and set aside.
Prep the veggies: Preheat the oven to 425°F (220°C). Toss sweet potato cubes and broccoli florets with 1 tablespoon olive oil, smoked paprika, cumin, salt, and pepper.
Roast: Spread veggies on a baking sheet.
Roast for 20–25 minutes, flipping halfway, until tender and lightly browned.
Crisp the chickpeas: Pat chickpeas dry. Toss with 1 tablespoon olive oil, a pinch of salt, and extra paprika or cumin if you like. Roast on a separate tray for 15–20 minutes until golden and slightly crunchy.
Make the dressing: In a small bowl, whisk tahini, lemon juice, maple syrup, garlic, salt, and pepper.
Add warm water a little at a time until you reach a pourable consistency.
Assemble the bowls: Add a bed of greens to each bowl. Spoon in cooked quinoa or rice. Arrange roasted sweet potato, broccoli, shredded cabbage, cucumber, avocado, and crispy chickpeas on top.
Finish: Drizzle with tahini lemon dressing.
Sprinkle with pumpkin seeds or sesame seeds and fresh herbs if using. Serve with lime wedges.
