Day 100 - Cheesy Tuna Muffin 'Wich

I wish I could have done something special for my 100th recipe, but I was driving through Colorado and Kansas at the time, so I had to settle for something I could eat on the road.  This was another tuna trio that was easy to throw together.  I would probably use a flavored cheese next time or add a little more flavor, it was just a little bland for me.  The 500 mile drive in the car probably didn't help either....
