Preheat your oven to 400°F.
Rinse and pat the chickpeas completely dry with a paper towel to ensure they get maximum crunch.
Toss the chickpeas with half of the olive oil and a pinch of sea salt on a parchment-lined baking sheet.
Roast for 20-25 minutes, shaking the pan halfway through, until the chickpeas are golden and crispy.
In a small jar or bowl, whisk together the tahini, lemon juice, and the remaining olive oil with a tablespoon of warm water until smooth and creamy.
Place the cooked quinoa, fresh spinach, diced cucumber, and halved cherry tomatoes in a large serving bowl.
Add the warm roasted chickpeas to the bowl and drizzle the lemon tahini dressing over the top.
Toss gently to combine all the flavors and serve immediately while the chickpeas are still warm.
