Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Roast the chickpeas. Toss the dried chickpeas with olive oil, smoked paprika, garlic powder, cumin, and salt. Spread on the sheet and roast for 20–25 minutes, shaking halfway, until crisp at the edges.
Start the lentils. Warm olive oil in a saucepan over medium heat.
Sauté onion for 3–4 minutes until softened. Add garlic and cook 30 seconds.
Spice it up. Stir in cumin, smoked paprika, chili flakes, and coriander. Toast 30 seconds to bloom the spices.
Simmer. Add lentils and broth.
Bring to a simmer, then reduce heat, cover, and cook 20–25 minutes until tender but not mushy. Season with salt and pepper.
Make the dressing. Whisk tahini, lime juice, maple syrup, garlic, and a pinch of salt. Add warm water a little at a time until pourable and creamy.
Taste and adjust lime or salt.
Prep the fresh toppings. Slice tomatoes, cucumbers, red onion, and avocado. Chop herbs. If using, heat cooked quinoa or rice.
Assemble the bowls. Add a base of greens and grains.
Spoon on the spiced lentils and roasted chickpeas. Scatter tomatoes, cucumber, and onion. Add avocado and herbs.
Finish with dressing. Drizzle the tahini-lime sauce and serve with lime wedges for a bright squeeze over the top.
