My favorite way to serve this meatless pastrami is to make a vegan pastrami sandwich!  After you cut the slices and simmer the pastrami, lay them on a slice of vegan bread and top the sandwich with pickles, lettuce, tomatoes, Russian dressing, vegan mayo, or spicy mustard.  Sauerkraut and rye bread make a great vegan reuben sandwich with a touch of spicy mustard.  It can be served as lunch or a light snack.
