I also find it disgusting the way the fast food joints slather condiments on their burgers. Yes, you can ask for them plain but then you realize just how thin and tasteless those burger patties are.
A really good burger does not need condiments other than maybe a thick slice of cheese and some sautéed onions or mushrooms. Or bacon.
I like a little mayo and pickles, and sometimes a fried egg. That’s it. A carnivore sandwich.
