ALL sandwiches are great. I can't think of too many I wouldn't eat, or actually too many I wouldn't consider delicious.
Below are some classics, some are cheap and sleezy, some are mainstream and overrated, some are perhaps haughty, and some are obscure.
Peanut butter and jelly-- especially grape, sour cherry, or wild blueberry jelly. Always served on cheap white bread.
Bologna-- again, always served on cheap white bread, with plenty of French's mustard. A bottle of root beer goes great with this pedestrian sandwich. (American bologna is foul by the way, must have German bolgna.)
Salami-- hard salami on sliced Italian bread with a slice of provolone and French's yellow mustard.
"Salad" sandwiches-- take your pick. They are all ridiculously delicious. Egg, ham, tuna, chicken, seafood, and all mixed with minced onion and minced red pepper and Hellmann's mayo.
Peanut butter and vidalia onion-- slice the onion thin and pile on the PB, served on quality white bread, along with sprinkled black pepper.
Veggie sandwich-- thin-sliced tomato, cucumber, green pepper, onion and lettuce with shredded carrot on a bulky roll, with plenty of cracked pepper & parmesan dressing.
Roast Beef-- rare RB sliced thin and piled high onto freshly baked wheat bread with lettuce, tomato, green pepper, onion, sprouts, and hot peppers, with Hellmann's mayo. NO cheese.
classic Hot Italian-- cappicola, baked or boiled ham, salami, provolone with shredded lettuce, tomato, and green pepper on a hard Italian or French baguette roll with "submarine" dressing.
Turkey-- fresh sliced turkey breast (from an oven-roasted turkey, still warm) with lettuce served on a local bakery rye with Hellmann's mayo and plenty of black pepper.
Sole-- deep fried sole filets on a white bulky roll with lettuce, sliced red onion and a good quality tartar sauce.
BLT-- served on whole wheat toast. Always a classic.
Western-- fried egg with onion and peppers on fresh white bread with a good dollop of ketchup.
Grilled cheese-- one slice of American and one slice of cheddar on buttered bread and grilled in the griddle. Do not burn bread, but make sure cheese becomes gooey. Easier said than done.
"Orgasmo" sandwich-- freshly sliced natural turkey, crisp bacon, lettuce, tomato, onion, mayo served in a Portuguese roll and grilled. Portuguese rolls are nutzoid delicious and may be taking the sandwich world by storm within the next couple years.
Club sandwiches-- always a favorite, especially with bacon.
Pastrami on rye with plenty of creamy coleslaw-- self explanatory.
Ham & swiss-- ham and swiss cheese combo is good on ANYTHING, including doggie poop.
Turkey & swiss-- great on a bagel, with french onion chip dip as a condiment.
Steak bombs-- enuffffff said.
"Weirdo" mini bombs-- one fat, breaded onion ring with nacho cheese spread in a dinner roll dipped in au jus.
Corned beef-- shaved thin and served on rye with brown mustard and a serving of coleslaw.
Open faced breakfast "sandwich"-- one freshly cooked Belgian waffle with Canadian bacon, melted Vermont cheddar cheese, creamy horseradish sauce and freshly shaved cold canteloupe.
