I only get Dunkin breakfast sandwiches when I'm in an airport - last time it was sausage and egg on a croissant. I didn't care for the croissant part of the sandwich - it would have been fine with different toppings I think. Just for me didn't work with the sausage and egg. I've also had the egg white sandwiches - and hated them.
I see now they're offering a smoked sausage and egg sandwich. the commercial last night made my mouth water, it looked so tasty.
What's your favorite?
