Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Thoroughly rinse and drain the chickpeas, then use a clean kitchen towel to pat them completely dry to ensure they achieve a perfect crunch.
Dice the chicken breast into uniform one-inch pieces and place them in a large mixing bowl along with the dried chickpeas.
Drizzle the chicken and chickpeas with avocado oil, then sprinkle with dried rosemary, dried thyme, sea salt, and black pepper, tossing well to coat.
Spread the mixture in a single layer on the prepared baking sheet and roast for 20 to 25 minutes, shaking the pan halfway through until the chicken is cooked and chickpeas are golden.
While the mixture roasts, heat a large skillet over medium heat and sauté the chopped kale with minced garlic for 3 to 5 minutes until the greens are tender and bright.
Divide the sautéed kale into serving bowls, top with the roasted chickpea and chicken mixture, and finish with a bright squeeze of fresh lemon juice.
