Preheat your oven to 400°F (200°C).
Drain and rinse the chickpeas, then pat them completely dry with a paper towel to ensure maximum crispiness.
Toss the chickpeas with a pinch of salt and cumin, then spread them on a baking sheet and roast for 20 minutes until golden and crunchy.
While chickpeas roast, season the chicken breast with salt and pepper and grill over medium-high heat for 6-7 minutes per side until cooked through.
Slice the grilled chicken into strips.
In a small bowl, whisk together the tahini, lemon juice, and a teaspoon of warm water until smooth and creamy.
Assemble the bowl by placing a base of fresh baby spinach and cooked quinoa.
Top with the sliced cucumber, halved cherry tomatoes, grilled chicken, and the crispy roasted chickpeas.
Drizzle the lemon-tahini dressing over the top and serve immediately.
