Burger toppings?

[FatFreddysCat]

I keep it fairly simple:
Cheese, ketchup, pickles. Occasionally a slice of tomato if the mood strikes me.

Me, personally, my choice:

Rare, no cheese.  Toppings: Lettuce, Tomato, Bacon, Mushrooms, Onions, sweet peppers.  Condiments: ketchup, spicy mustard and a touch of red pepper flakes.

I like it all on an onion bun if I can.

I like lettuce, tomato, thin slice raw onion, mayo and dab ketchup on medium rare cheese burger.

I'm pretty plain with my burgers, cheese and ketchup usually.  I do occasionally like a fried egg and mayo too, but that's not too uncommon 'round these parts.  

I like 'em plain too, but always with cheese. 

I do have a follow-up question though - Do you think there is a correct order to assemble a cheeseburger? ...

Yes.  Mayo on both sides of hard roll, raw onion on bottom, ketchup dab, hot cheese burger on top of that, tomato slice, lettuce, lid.
