In medium skillet, brown ground beef with 1/4 cup chopped green pepper. Sprinkle with some seasonings.
In another larger skillet, place potato cubes, red onion, 1/4 cup bell pepper and some seasonings and cover, stirring occasionally on medium-low heat until potatoes are soft.
Once ground beef mixture is done, drain well and then stir into potato mixture. Add in cheddar cheese, cover, and simmer on low heat until the cheese is melted. Stir well and serve immediately with a green salad and warm bread.
