Yup fajitas are best- I tell them light on oil and seasoning also
What I hate is when you say "no tortillas" and they bring it anyways- if I were rude I'd snap and say "I SAID NO TORTILLAS" lol. I just put it on the other side of the table and don't touch them
Some restaurants do great salads too- I ask for dressing on the side or for them to use half the amount of dressing
