Cut the tops off the peppers, remove seeds and membrane. I halved the recipe when I made this so I started with 4 peppers but ended up using 5.
Place the peppers in small amount of boiling salted water, cover, and steam for 5-10 minutes, drain. Sprinkle insides with salt.
In a large non stick pan, brown the ground beef and onion.
To the pan, add the corn, tomato sauce, Worcestershire sauce, salt, and MSG, simmer until heated through, about 5 minutes.
Preheat your oven to 180° C (350° F), get out a 9x13 inch baking pan. If cutting the recipe in half, use a 8x8 or 7x11 inch baking pan.
Add the cheese to the beef mixture and stir until melted.
Fill peppers and place upright in the baking pan. Mix together the bread crumbs and melted butter and sprinkle on top of each pepper.
Bake for 40 minutes or heated through.
Serve and enjoy.
