Spread both pieces of bread with spread - (* if you plan to eat this sandwich at a later time, this will prevent the bread from soaking up the mayo, mustard and liquids from the vegetables. Omit if you desire). Spread the mayonnaise and mustard on slices of bread to your preference. Distribute veggie's and slice(s) of "cheese," cover with tomato and lettuce and either top with second slice of bread or eat as an open faced sandwich.
*For a non-gluten meal use millet or rice bread.
Other vegetable options might include: sprouts, shredded carrots, avocado, onion, pickles, roasted red peppers, zucchini, etc.
Serve with carrots and celery, corn chips and a piece of fruit.
