Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse and pat the chickpeas dry, then toss them with a half-teaspoon of olive oil and the dried oregano.
Roast the chickpeas for 20-25 minutes until they are golden and crisp.
Season the turkey breast with a pinch of salt and pepper, then grill over medium-high heat for 5-7 minutes per side until the internal temperature reaches 165°F.
Let the turkey rest for 5 minutes before slicing it into thin strips.
In a large salad bowl, combine the mixed greens, cherry tomatoes, and sliced cucumber.
In a small jar, whisk together the remaining teaspoon of olive oil and the lemon juice to create the dressing.
Drizzle the dressing over the salad greens and toss to coat evenly.
Top the salad with the grilled turkey slices and the warm roasted chickpeas.
