Preheat oven to 350 degrees F. Lightly grease or spray a 2 or 2 1/2 quart oblong casserole dish.
Brown ground beef, half of the bell peppers and onion in a heavy skillet over medium-high heat. Drain fat from pan, reduce heat.
Add the undiluted tomato soup, corn and the cream cheese. Stir until well combined and no chunks of cream cheese are visible. Stir in taco seasoning and 1 cup of the shredded cheese. Turn mixture into prepared pan, spreading mixture evenly across the bottom.
In a separate bowl, combine the defrosted hash browns, the remaining peppers, salt, pepper and remaining 1 cup shredded cheese.
Top ground beef with potato mixture, pressing it down slightly.
Bake at 350 degrees F for 30-35 minutes or until topping is browned and crispy on top.
