Slice the potato into medium thick slices (you will have leftover potato so I suggest you bake the rest and save it for later). Layer about 3-5 slices (more or less to your preference) between pieces of vegan bread. Cover in foil and bake for 45 minutes to 1 hour or until potatoes are tender. Go read a good novel while this is baking. You can probably polish off Of Mice and Men. After potatoes are to your liking, open sandwich and top with soy cheese, sliced tomatoes and seasonings. Replace top slice of vegan bread and either bake or broil (if you want to toast your vegan bread) for about 5 minutes or until cheese is melty. I love to eat this for lunch or breakfast with orange juice.:)
