Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse and thoroughly dry the chickpeas with a paper towel to ensure they get crispy.
Toss the chickpeas with one teaspoon of the olive oil and a pinch of sea salt, then roast for 20-25 minutes until golden and crunchy.
Season the turkey breast with dried oregano, salt, and black pepper.
Grill the turkey over medium-high heat for 5-6 minutes per side or until the internal temperature reaches 165°F.
While the turkey rests, whisk together the remaining olive oil, a squeeze of fresh lemon juice, and a teaspoon of Dijon mustard to create the vinaigrette.
In a large bowl, combine the mixed greens, cucumber, and cherry tomatoes.
Slice the grilled turkey into strips and arrange them over the salad greens.
Drizzle the vinaigrette over the top and garnish with the crunchy roasted chickpeas.
