How many calories are in two slices of brown bread and one egg sandwich?

The total ingredients used to make a ham and tomato sandwich and the quantities/weight of those ingredients (ham, tomato, bread, butter, etc.) determine the calorie content of the sandwich. Please feel free to ask the question again and include those weights. Meanwhile, for the calories in ham, and the calories in tomato, see the page links, further down this page, listed under Related Questions.
