calories in a small slice of roast beef
There are about 50 calories per ounce in roast beef. It depends on how many ounces of beef you use on your sandwich. No not 50 calories it is 400 calories in a roast beef sa â¦ ndwitch because if you put more than that on it you will get fat. The answer above mine is a great example of what not to take into consideration when thinking about nutrition.
