Preheat oven to 400°F and line a large baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them very dry with a clean kitchen towel to ensure maximum crispiness.
Cut the chicken breast into bite-sized half-inch cubes to match the size of the chickpeas.
In a large mixing bowl, combine the chicken, chickpeas, avocado oil, minced garlic, oregano, thyme, sea salt, and black pepper.
Toss thoroughly until everything is evenly coated in the oil and spices.
Spread the mixture in a single layer on the baking sheet, ensuring no pieces are overlapping.
Roast for 20 to 22 minutes, shaking the pan halfway through, until the chicken is golden and the chickpeas are slightly crunchy.
Remove from the oven and immediately drizzle with fresh lemon juice to brighten the savory flavors.
