When you go to McDonald's and wants to order a hamburger but dry, meaning no sauces, no vegetables and no other extras. What's the exact phrase for that in English?

I just remember having a problem with it in restaurants. I always wanted to order meat, but without various sauces and vegetables in it. It might be put aside. The waitress never understood me. Does this have a different expression in English that is accurate to say that it would be obvious what I want?

Saying dry hamburger isn’t working :-/
