why do we need to include low fat filling in a sandwich
There are 26 grams of fat in the McDonald's McRib sandwich.
Fat content could be high in a fish sandwich if the fish was deep-fried. There is also fat content in tarter sauce or dressing as well as in the bread or bun used for the sandwich. If the sandwich includes cheese, the fat content would be even higher.
WATER!It is filling and has no calories.
That depends on how much butter you spread on the bread when making the sandwich.
Low fat means "less than or equal to 5% fat" - thus the amount of mayonnaise that you put in can not make the fat content of the sandwich exceed 5% (i.e not more than 5 grams of fat per 100 grams of sandwich). Thus the amount will vary according to the type of mayo that you're using, and whether the sandwich has any other fatty fillings (such as cheese).

cheese
Depends on the kind of cheese.

Well, this depends. How much ham and cheese is on the sandwich? And, are there two pieces of bread, or 4? Wheat, or Rye? Low-fat cheese?
