Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Drain and rinse the chickpeas, then roll them between two clean kitchen towels until they are completely dry to the touch.
Dice the chicken breast into small pieces, roughly the same size as the chickpeas, to ensure even roasting.
In a large mixing bowl, combine the dried chickpeas and diced chicken with avocado oil, garlic powder, dried oregano, sea salt, and black pepper.
Spread the mixture in a single layer on the prepared baking sheet, making sure the pieces are not touching.
Roast for 22 to 25 minutes, shaking the pan halfway through, until the chickpeas are crispy and the chicken is golden brown.
Remove from the oven and immediately toss with nutritional yeast and freshly chopped parsley while still hot.
