Cook the quinoa: Rinse quinoa under cold water.
Add it to a pot with water or broth and a pinch of salt. Bring to a boil, reduce to low, cover, and simmer for 15 minutes. Turn off heat and let it sit, covered, for 5 minutes.
Fluff with a fork.
Roast the vegetables: Preheat oven to 425°F (220°C). Toss sweet potato, broccoli, bell pepper, and red onion with olive oil, smoked paprika, cumin, salt, and pepper. Spread on a baking sheet and roast 20–25 minutes, tossing once, until tender and lightly browned.
Prepare your protein: If using chickpeas, pat dry and toss with a little olive oil, salt, and pepper.
Roast on a separate tray for 15–20 minutes for extra crunch, or leave as is for a softer texture. If using tofu, toss cubes with a teaspoon of soy sauce and a drizzle of oil; bake 20–25 minutes until golden.
Make the dressing: In a small bowl, whisk tahini, lemon juice, maple syrup, and garlic. Add warm water, 1 tablespoon at a time, until pourable.
Season with salt and pepper. It should be creamy but not thick like paste.
Prep fresh veggies: While the oven works, slice avocado, shred carrot and cabbage, halve tomatoes, and chop herbs. Keep portions small and bite-sized for easy eating.
Assemble the bowls: Add a base of quinoa and mixed greens to each bowl.
Top with roasted veggies, your protein of choice, cabbage, carrot, and tomatoes. Add avocado and sprinkle with seeds and fresh herbs.
Dress and serve: Drizzle with the tahini-lemon dressing. Taste and add a pinch of salt, a squeeze of lemon, or a dash of hot sauce if you like heat.
