Plain bread, any cheese and salt & vinigar crisps!
That or toasted bread with cheese and tuna...

my sandwich is..
Italian bread, turkey burger, cheddar cheese, and Italian seasoning!!
cook the turkey burger on your stove top
cut it into slices
put it in the Italian bread
sprinkle the cheese and seasoning on top of the sandwich
put it in the oven until it is crispy!!

My best and favorite sandwich is a Grilled Reuben

Rye Bread
Corned beef
Sour Kraut
Russian Dressing
Swiss Cheese

Heat up Kraut and Beef in Frying Pan. in separate pan put Butter side of rye down and put Russian Dressing on open face of bread and put Swiss and Kraut and Beef on the bread. and Grill until rye is toasted. Close sandwich cut and plate. and add Pickle on side.

It depends on my mood. Sometimes my favorite is

roasted turkey breast, mayo, cheese(Havarti, Gouda, Tillamook medium cheddar, avocado,
tomato,fresh basil (moody about the basil), or green leaf lettuce. Sometimes I like
crispy bacon on it (other times my inner Jew prevents
me from eating pork). (Love Sheepherder bread, sourdough
or whole grain, croissants so the bread varies). Oh yes and
dill pickle slices.

I also make a great French Dip or steak (filet mignon) sandwich.

I am not a person who regularly eats sandwiches.
I still love pb&j as well as a grilled cheese.
I love grilled cheese with fresh slices of tomato.

A Carne Asada Taco or Fish taco might qualify as my favorite!
