I just remembered a really weird type of sandwich that they used to sell at a food truck at college. I forget the name (of the sandwich. The truck was called Pyramid Pizza) and I've never tried to put one together myself but it seems rather elementary...
You'll need:
2 hotdogs
a hoagie/hero/grinder/sub roll
french fries
Ketchup
Cheese whiz
Honey mustard
Directions:
1.) Heat up hotdogs and fries
2.) Lay hotdogs end to end in hoagie/sub/grinder roll
3.) add ketchup, mustard, and cheese-whiz
4.) jam fries into roll above hotdogs
5.) garnish with more ketchup, mustard, and spray cheese
This was one of the less weird sandwiches that they sold.
