Tuna Turner (my version of a tuna melt)
 
Tuna mix:
big can tuna
1/2 large onion, chopped fine
1 large stick celery, chopped fine
1/4 cup homemade mayonnaise
1/4 cup sour cream (half the calories of mayo, adds lots of flavor)
1 fatty spoonful yellow mustard
salt & pepper
Old Bay if you really want to do it up brown
and here's the absolute kicker:
handful of grated cheddar (YES! mixed right in!)

two thin slices of homemade bread, buttered very lightly on outsides
1/4 to 1/3rd of the tuna mix, spread
3-4 minutes in a George Foreman grill, turn back-to-front during
