The only topping I actively prefer on my burgers are onions. Lettuce I am fine with, but it's not something I actively seek. Anything else I'd rather not have on my burger.
I want basically all of the toppings, to the point that it's more salad than burger. Lettuce and cheese (preferably pepperjack) are a must have. My food preferences have a lot to do with texture and lettuce gives the burger the crunchiness it needs to be tasty. I also enjoy really flavorful toppings like onion, pickle, or jalapeño if I'm feeling spicy. (I usually am. I love spicy foods!)
I'll have a fried egg on my burger only if I have the patience for it-- they're tasty but so, so messy, haha. I used to pick tomato slices off my burgers, but lately I've been coming around to them. A single slice is fine if there are enough toppings on the burger for them to blend in. The only toppings I wouldn't go for on this list are probably mushrooms and relish.
The standard toppings will be lettuce and a thin slice of tomato. From there I would have to choose a combination from onions, avocado, bacon, ketchup, thousand island dressing, mustard, or pickles.
I don't like too many flavors on my burger, so I just stick with simplicity and get one with lettuce, cheese, and the house dressing, if it's available.
One time I tried a burger with tomatoes and grilled onions, and it was a bit too much for me. Plus, it was too big and I don't wanna open my mouth very wide for it.
When it comes to hamburguers I really like cheese. In fact, I require it. It can be amy kind but I prefer sharp cheddar, mozzerella, feta or goat cheese right now. As for the veggies, I like lettuce, tomato, pickles and onions. Onions can be either caramelised or raw but I prefer caramelised more.
I usually choose cheese, vegetarian patty, lettuce and tomatoes as ingredients. As for the sauce I enjoy ketchup and mustard if anything. I am not really a burger enjoyer because it is always so messy.to eat!
Having condiments with or toppings on food usually doesn't appeal to me much, so my burgers are always pretty basic and plain Jane; I just like cheese on them. I don't mind red/white onions, bacon, lettuce or even fries/onion rings as toppings, and sometimes I'll have ketchup on the side, but 99.9% of the time I just want cheese lol
Fried egg on a burger looks delicious, though! I definitely want to try that someday.
Cheese, ketchup, onions and bacon would probably be my safe 'go to' toppings. But I would happily have pickles, mushrooms, even avocado on rarer occasions! Lettuce is fine but I'm not miffed about it either way.
