The kids around here like this one and it's simple to make:
1 cup mayo
1/4 cup fresh chopped herbs such as parsley, basil or chives
12 slices Smoked Turkey Breast
8 slices Swiss Cheese
16 slices Thick Cut Bacon, cooked and drained
1 tomato, cut into 2 slices per sandwich
8 slices sourdough or Tuscan bread
3 tablespoons butter, softened
Combine mayo and herbs; set aside.
Place 3 turkey slices, 2 cheese slices, 4 bacon slices and 2 tomato slices on half of the bread slices. Spread remaining bread slices with mayo mixture; place, mayo sides down, on tops of sandwiches.
Spread the outsides of sandwiches with butter.
Brown in a skillet on medium heat until lightly brown on both sides.
