At In-N-Out Burger, ask for Protein-Style, but with catsup and mustard instead of spread; fewer calories, less crap, better health.
While you're at it, go for extra tomatoes and throw on some pickles!
I get it without sauce and with only mustard, not ketchup...I don't like all the sugar (well, HFCS) in ketchup. Definitely add pickles and onions, though. Yum.
