Mix sausage, cheese, bread crumbs, salt and pepper, and egg together in mixing bowl. Season to taste. Adjust mixture with additional cheese and bread crumbs if too dry or moist - medium moisture for stuffing desired. Make a radial slice around the top of the banana pepper leaving the top intact. Pull back top and remove seeds if so desired. Gently stuff mixture into peppers. Place olive oil in hot saute pan. Gently place peppers in the pan and fry each side until browned. Place marinara sauce in middle of plate. Arrange peppers on top of marinara and grate the dry ricotta cheese on top of the hot peppers.
