Preheat your oven to 400°F (200°C).
Rinse and drain the chickpeas, then pat them dry with a paper towel. Toss with olive oil, cumin, salt, and pepper.
Peel and dice the sweet potato into small cubes. Toss the cubes with a little olive oil, salt, and pepper.
Spread the chickpeas and sweet potato cubes on a baking sheet lined with parchment paper. Roast in the preheated oven for 20-25 minutes, or until chickpeas are crispy and sweet potatoes are tender, stirring halfway through.
While the chickpeas and sweet potato roast, steam or boil the shelled edamame for about 5 minutes until tender. Drain and set aside.
In a small bowl, whisk together tahini, lemon juice, a pinch of salt, and a few teaspoons of water (if needed) until you reach a smooth, drizzling consistency.
Assemble the bowl by placing the baby spinach at the base, then topping with roasted chickpeas, sweet potato cubes, and edamame. Drizzle the creamy lemon tahini dressing over the bowl.
Serve warm and enjoy your balanced, protein-packed meal.
