That yellow mustard just ruins a burger...and I enjoy some WEIRD burger toppings!
Did you know that in Lansing, Michigan, they serve an OLIVE burger? They make a sort of tartar sauce with chopped green olives and mayo, and serve that on top of the burger with lettuce and tomato!
@helenS The first restaurant I cooked in (1982) had a "Hawaiian Burger" on the menu: a quarter-pounder topped with bacon, cheese and pineapple! It was actually very tasty! 😆
Plastic cheese. You know those crappy cheese slices that turn to sticky slime when they melt? Just use normal cheese. Don't get me started on the bread rolls lol
