I adopted the recipe from Kraft--tried it, loved it. I usually make the tuna filling ahead of time and heat it up for quick lunch
- Mix tuna, mayo, onion, green pepper and seasonings.
- Cover each of 4 bread slices with tuna mixture, 1 cheese slice and second bread slice.
- Spread outsides of sandwiches with additional mayo or softened butter.
- Cook in skillet on medium heat until lightly browned on both sides.
