Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse and pat the chickpeas very dry with a paper towel, then toss them with half of the olive oil and a pinch of cumin or sea salt.
Roast the chickpeas for 20-25 minutes until they are golden and crunchy.
While chickpeas roast, brush the turkey breast with the remaining olive oil and season with garlic powder and black pepper.
Grill the turkey breast over medium-high heat for about 5-6 minutes per side until fully cooked through.
In a small bowl, whisk together the tahini, lemon juice, and a tablespoon of warm water until the dressing is smooth and pourable.
Assemble the salad by placing the mixed greens, sliced cucumber, and halved cherry tomatoes in a large bowl.
Slice the grilled turkey into strips and place them on top of the greens.
Finish the dish by sprinkling the crunchy chickpeas over the top and drizzling with the lemon tahini dressing.
