Cut tops off bell pepper. Save to use later if you want to, cut out seeds.
Blanch peppers in boiling water for five minutes to soften.
Remove, put in ice bath, cool.
Mix ground beef with eggs, bread or breadcrumbs, parsley, cheese, salt and pepper.
Put tomato sauce into baking dish. I used a dutch oven. You can use either a baking dish or dutch oven. The sauce should come about half way up the peppers.
Put in oven at 400 degrees uncovered for twenty minutes. Reduce heat to 325. Cover and bake for at least one more hour, or until peppers are softened.
