Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Drain and rinse the canned chickpeas, then pat them very dry with a clean kitchen towel to ensure they get crispy.
Slice the chicken breast into thin, bite-sized strips so they cook at the same rate as the chickpeas.
In a large bowl, toss the chickpeas and chicken strips with the olive oil, garlic powder, sea salt, black pepper, and dried parsley until evenly coated.
Spread the mixture in a single layer on the prepared baking sheet, ensuring there is space between the pieces for even roasting.
Roast for 20 to 25 minutes, tossing halfway through, until the chicken is cooked through and the chickpeas are golden and crisp.
Remove from the oven and immediately sprinkle with the grated parmesan cheese so it melts slightly over the warm ingredients.
