Preheat your oven to 400°F (200°C) to prepare the chickpeas.
Rinse and thoroughly pat the chickpeas dry with a paper towel, then spread them on a baking sheet and roast for 20-25 minutes until crunchy.
Season the turkey breast with a pinch of salt, pepper, and garlic powder.
Grill the turkey over medium-high heat for 5-7 minutes per side, or until the internal temperature reaches 165°F.
Allow the turkey to rest for 5 minutes before slicing it into thin, bite-sized strips.
In a small bowl or jar, whisk together the olive oil, lemon juice, and Dijon mustard to create the vinaigrette.
Place the mixed greens, halved cherry tomatoes, and sliced cucumber in a large salad bowl.
Add the grilled turkey and roasted chickpeas on top of the greens.
Drizzle the lemon vinaigrette over the salad and toss gently to combine before serving.
