I love Subways. Good bread, fresh veggies, a nice filling (Tuna is my favourite) and a layer of cheese. Everything good in one filling meal. But how to eat a sub without looking like a mustard splattered monster is another thing.
My favourite tip: Open up the subway sandwich and eat the vegetables first (with a fork). Once you have completed this delightful task, you are left with a much more manageable cheese + meat/tuna/aloo patty/paneer tikka + bread sandwich. Far neater, far more enjoyable! Save the best for the last of course.
I have to say, I love the way Subway uses a layer of cheese to segregate the meat from the veggies — keeps the vegetables crisp much longer!
