Preheat the oven to 350 degrees F. Combine all ingredients except chicken and oil in a plastic bag. Place chicken cubes in the bag and shake well.
Place the cubes on a nonstick cookie sheet. Drizzle olive oil over the cubes, or mist lightly with olive oil from a spray bottle. Bake the cubes for about 10 minutes until chicken is cooked through and tender. Serve cold.
