Preheat oven to 375 F.
Meanwhile, wash your peppers and cut the tops off.
In a medium bowl, mix the breadcrumbs, eggs, cheese, herbs, olive oil, salt and pepper and mix well with the beef.
Carefully stuff each pepper with the seasoned beef mixture.
Place in an oven proof dish/pan.
Add a little water (about ¼ cup maybe) to help steam them, cover and bake for 60 -90 minutes until the peppers are extremely soft and beef is cooked to at least 165F.
