Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Rinse and drain the chickpeas, then pat them completely dry with a paper towel to ensure maximum crispiness.
Toss the chickpeas with half of the olive oil, sea salt, black pepper, oregano, and garlic powder.
Spread the chickpeas on the baking sheet and roast for 20-25 minutes until golden and crunchy.
While chickpeas roast, season the chicken breast with the remaining salt and pepper and grill over medium-high heat for 6-7 minutes per side until cooked through.
In a large bowl, massage the kale with lemon juice and the remaining olive oil until the leaves soften.
Slice the grilled chicken into strips and add them to the kale bowl.
Top the salad with the warm, crispy roasted chickpeas and serve immediately.
