I texted the KGB (not the Russian one), and asked if a Taco was considered a sandiwch.  I also asked if a hot dog was one due to curiosity, and here is what was replied.
 
 
  "Tacos & Quesadillas are part of the sandwiched & stuffed category of human foods. Hot Dogs were originally called meat sandwiches!- KGB_Team"
 
 
Boom.
