in high school, I spent a summer in Germany as an exchange student(school was still in session there). The family I stayed with sent us(me and their son) to school w/packed lunches every day. The main portion was a sandwich that consisted of a small pretzel roll filled w/cured ham and cheese. Your post reminded me of those rolls. Thank you!
