Many people ask why as a Vege you would want to eat something that is imitating meat. I would say most vegetarians did not stop eating meat beacuse it tasted bad. There are dozens of other reasons to do so.
I am a vegan, but enjoy eating a wide range of tastes and textures. Meat analogs are another sorce of that. As well sometimes it is nice to enjoy a vegan version of food others are eating around you. Hotdogs, hamburgers, deli meat, turky on thanksgiving, meatballs in pasta, the list goes on.
Some of my favorite's: Boca Burgers, Tempeh Bacon (Fakin Bacon) Chicken-free nuggets, Soy Sausage, Tofurky deli meat, yummy seitan things, any of the great soy dogs on a toasted bun with all the fixings. Vegweb is a great site for recipes.
