Preheat oven to 425 degrees F (220 degrees C).
Rub roast with 1tbsp salt.
Combine parsley, sage, rosemary, garlic, black pepper, onion flakes and 1tbsp salt in a medium bowl.
Add breadcrumbs and oil to the herb mixture. Should be a consistency that will stick to the meat.
Press breadcrumb mixture onto sides of the pork until there is no pink showing (usually 1/4' thick).
Bake for at least 35 minutes until a meat thermometer reads 165 degrees F (75 degrees C) or until there is no pink when the pork is cut.
Let the pork rest for 10 minutes, then cut into 1/2 inch slices.
