Preheat your oven to 400°F (200°C).
In a mixing bowl, combine the drained chickpeas with olive oil, paprika, garlic powder, cumin, salt, and pepper. Toss until the chickpeas are evenly coated.
Spread the chickpeas in a single layer on a baking sheet. Roast in the oven for 25 minutes, or until they are crispy and golden brown, tossing halfway through for even cooking.
While the chickpeas are roasting, prepare the salad. In a salad bowl, combine the mixed greens, cherry tomatoes, cucumber, red onion, and feta cheese (if using).
Once the chickpeas are done roasting, add them to the salad mixture.
Drizzle the balsamic vinaigrette over the salad and toss gently to combine.
Serve immediately and enjoy!
