In a large bowl, add the corn, breadcrumbs, Parmesan cheese, chopped cilantro, onion, and jalapeño (if you like a little extra spice). Then, sprinkle in the chili powder, cumin, garlic powder, and a pinch of salt and pepper. Now crack the egg into the bowl and mix everything together until well combined. You should have a mixture that holds together when you shape it into small balls.
