>>9061377Hamburgers are great.
Bacon is delicious and its flavor profile combines exceptionally well with burger meat.
Add a slice or two of American cheese and you've got a burger approaching maximum deliciousness.
Purple onions (red onions?) are also an option.
They seem to work well in terms of flavor mixing and add a crunchiness to the burg.
Lettuce can also be a workable addition sometimes.
Tomato's are a common topping though I think many times you are better off without them, slice them thinly and make sure they're of proper ripeness if you're gonna add them.
