Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Pat the chickpeas dry with a paper towel, toss them with half of the olive oil and a pinch of salt, then roast for 20 minutes until they are golden and crisp.
Season the chicken breast with salt, pepper, and any desired dried herbs like oregano or garlic powder.
Heat a grill pan or outdoor grill over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken and chickpeas cook, prepare the dressing by whisking together the tahini, lemon juice, and a teaspoon of warm water until smooth and creamy.
Slice the grilled chicken into strips or bite-sized cubes.
In a large bowl, layer the baby spinach, cooked quinoa, cucumber, and cherry tomatoes.
Top the salad with the grilled chicken and the warm roasted chickpeas.
Drizzle the lemon-tahini dressing over the top and serve immediately.
