Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them thoroughly dry with a clean kitchen towel to ensure maximum crispiness.
Cut the chicken breast into small, uniform half-inch cubes to match the size of the chickpeas.
In a large mixing bowl, combine the cubed chicken, dried chickpeas, and extra virgin olive oil, tossing until everything is well coated.
Add the smoked paprika, ground cumin, sea salt, black pepper, and garlic powder to the bowl and toss again to distribute the spices evenly.
Spread the mixture in a single layer on the prepared baking sheet, making sure the pieces are not crowded.
Roast in the oven for 20 minutes, then remove the tray and toss the ingredients with a spatula.
Sprinkle the pumpkin seeds over the tray and return to the oven for an additional 5 minutes until the chicken is cooked through and the chickpeas are golden.
Allow the mix to cool for 2-3 minutes on the tray to let the chickpeas crisp up further before serving.
