1 Tbsp. mayonnaise (I love Kraft light)
1 tsp. prepared mustard
4 slices sandwich bread (your choice, I used white wheat)
2 slices cooked turkey
2 slices cooked ham
2 slices Swiss cheese
1/4 cup sour cream
2 Tbsp. half and half
½ cup fine, dry breadcrumbs
Combine mayonnaise and mustard, spread lightly on one side of each bread slice.
Place one slice each of turkey, ham, and Swiss cheese on top of 2 bread slices. Top with remaining bread. Cut each sandwich in half diagonally.
Beat eggs; add sour cream and half and half, whisk well.
Dip sandwich halves in batter; coat with breadcrumbs. Carefully lower sandwich halves, one at a time, into pan that butter has been melted in over medium heat cook until golden brown, turning only once. Drain on a paper towel. Serve immediately.
