I rather think the British idea of a sandwich is very different from the American idea, but these are fillings we all enjoy. The sandwiches are made from two slices of wholemeal (wholegrain) bread, and no butter or margarine is used. All are seasoned to taste.
Low-fat cream cheese and sliced tomatoSpread the bread with reduced-calorie mayonnaise, add ham (low-fat!), lettuce,cucumber, etc.
Leftover cold fish pie (I'll send the recipe to any who want it!) which sounds counter-intuitive, but it's almost worth making fish pie just for the sandwich filling!
Low-fat cream cheese and smoked trout or salmon Cottage cheese (any flavour) and cucumber Reduced-fat Cheddar cheese and Branston pickle
