I already talked about my favorite sandwich in the other forum, but if I had to choose a Top 3, here they are:
1) 3-Cheese Grilled Cheese Sandwich at the Toasteria Cafe'
2) Jimmy John's Vito (SALAMI, CAPICOLA & PROVOLONE onion, lettuce, tomato, oil & vinegar, & oregano - basil)
3) Roasted Turkey and Cheese Panini at Panera Bread (if they make it right, but lately the quality of their food has gone down)
I'm going to start researching this more, and start trying more sandwiches.
