i've been a vegetarian for ten years, and my fiance switched about 2 years ago. eating out is sometimes a challenge, but burgerking and mcdonalds have veggie burgers (i don't eat them, but they do have them) plus at resturants, you can always try spaghetti with marinara, any pizza without meat, a baked potato with cheese and broccoli or sour cream, eggs and hashed browns.
many places offer rice or vegetarian refried beans, as well. not to mention chips and salso, potato salad, pancakes.
my favorite meal... maybe pasta with a sour cream and tomato sauce i make myself. or maybe thai noodles of some kind. there are also a few veggie steaks at most health food stores that are really good, and boca makes burgers and chicken that i have fed to people who couldn't tell they weren't meat.
my son is not a vegetarian, but he still loves to eat morningstar farms veggie corndogs, which he says has a taste and texture that rock. they also make a great chicken pot pie with their veggie chicken, and my fiance goes crazy for their sausge patties. their stuff is available in literally every supermarket in l.a. county that i've ever seen.
