I'm vegetarian and I love Subway. They have a Veggie Delight with 3
grams of fat, 9 grams of protein and 230 cal. total for the 6-inch. If
you need to take kids out, McDonald's side salad is pretty good for $1
although the tomatoes are often soft. I buy a couple of those salads.
They have 15 cal each and essentially no fat or protein.

At home, if you use Sara Lee's Delightful bread that comes in whole
wheat, honey whole wheat and multigrain, there is only 45 cal per slice
which is about half the calories of most bread for the same size slice.
It is quite good, too. It also contains 3 g of protein per slice. I
love it.

Except for Subway and McDonalds, I am usually disappointed eating out
because I cannot get exactly what I want. They put salt or cheese or
oil or who know's what in their food so that you cannot know the fat,
protein, salt, calories very accurately. Salad bars may be safe though.
It is entirely possible to be vegetarian and eat a terrible diet that
is high in fat, sugar and salt and low in protein, if you are not
careful, which is likely what you will find in most restaurants.

Most of the things I eat are not restaurant fare....oatmeal, egg
whites, lactose-free milk, blueberries, cabbage (without bacon or salt
flavoring), green beans (without salt or butter/margarine), brown rice,
plain fruit and vegetables.

The biggest problem I have being vegetarian though is dealing with
family and friends who do not respect my food choices and try to foist
their idea of vegetarian food on me by selecting a restaurant that has
nothing I can eat, feeling slighted if I don't eat their food, or
constantly reminding me that a little meat or whatever won't hurt me,
or I'm too thin, or telling me that vegetarian diets are no healthier
than other diets, etc. etc.
