Been completely vegetarion for over a year now, and have since found a great replacement for bacon; shiitake bacon! It totally livens up salads and baked potatoes. Prep is crazy simple, too, and almost every grocery store carries shiitake.
1. destem mushrooms leaving the gills intact, discard stalks
2. thinly slice mushroom caps
3. place in medium bowl and coat with soy sauce (whorchester, or maggi are good as well), allow to marinate for a min. of 10 minutes
4. drain "bacon" and spread on baking sheet; bake at 350 until roasted (about 15mins)
5. om nom nom
