Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Drain and rinse the chickpeas, then pat them extremely dry with a clean kitchen towel to ensure they achieve maximum crispiness.
Dice the smoked turkey breast into small, uniform cubes roughly the size of the chickpeas.
In a medium mixing bowl, combine the dried chickpeas and diced turkey with the extra virgin olive oil, garlic powder, smoked paprika, sea salt, and black pepper.
Toss the mixture thoroughly until every piece is evenly coated with the oil and spices.
Spread the mix in a single layer on the prepared baking sheet, making sure not to overcrowd the pan so the air can circulate.
Roast for 25 to 30 minutes, giving the pan a good shake halfway through, until the chickpeas are golden and the turkey bits are crisp.
Remove from the oven and immediately sprinkle with the nutritional yeast, tossing well while the mix is still hot so the yeast adheres to the ingredients.
