Eat plenty of raw bananas, apples, oranges, and grapes, and drink their juices. Fruits are the best part of a vegetarian diet. Also, eat plenty of peanuts, sunflower seeds, and other assorted nuts. Nuts are an excellent source of protein. Peanut butter sandwiches on whole wheat bread are great.

Being vegetarian does not mean you cannot eat prepared foods just make sure they don't contain animal ingredients or by-products. I enjoy ice-cream. You can also eat butter, so you can enjoy buttered toast with your coffee or tea in the mornings. There are also some cheeses made without rennet, which comes from the stomach of cattle. Tillamook is one company that produces cheese without rennet. Check the labels when you buy processed foods.

I am quoting myself to clarify that when I wrote that you can eat prepared foods without animal ingredients or by-products I meant that do not involve the killing of animals. This is why it is alright for a vegetarian to eat cheese and butter and drink milk because these foods do not require the destruction of the animal's life.
