I ordered tuna sandwiches from Subway, Jimmy John's, and Jersey Mike's to find the best one.Steven JohnI tried classic tuna sandwiches at Subway, Jimmy John's, and Jersey Mike's to find the best one.Subway and Jersey Mike's both had OK offerings, but there were problems with both.Jimmy John's sandwich had a great balance of ingredients and spot-on taste and texture.I think ordering a tuna sub is always going to be a bit of a risk.
