There's a difference between ordering a salad because you like salads and ordering one because you want to look like an anorexic waif. It's pathetic to try and base every single thing you do off of what you think a guy will want to see. People like to share experiences, which includes eating. If a guy likes barbecue and all you ever eat is salads, and then he meets a girl who loves bbq... guess who he'll want a second date with?
If you want to eat salads and have a guy love it, go date a vegan.
