Whisk the cornmeal, water, and salt together in a medium saucepan, and place over medium to medium-high heat.
Bring to a boil, then cook, stirring almost constantly, for 15-20 minutes, or until the polenta is thick and sticky.
Stir in the cheese, garlic powder, and Italian seasoning.
Remove the polenta from the pot and place onto plastic wrap or in a baking dish sprayed with olive oil or cooking spray.
Shape into a rectangle, about 1/2 in. thick, wrap in plastic wrap, and place in the refrigerator until cooled.
Preheat your oven to 450°F.
Cut the polenta into 1/2 in. cubes, and place in a single layer, not touching, on a baking sheet coated with olive oil or cooking spray. Spray some more olive oil or cooking spray over the cubes.
Bake for 25-30 minutes, turning every 8-10 minutes, until browned and crispy.
Serve over your favorite salad.
