We have friends that order pizza like 3 nights a week all because of their 11 year old son. They only go to restaurants that serve Kraft mac n cheese-TGI fridays, Texas Roadhouse. He won't eat at other chains like Carrabas, Outback steakhouse, etc.
When we are at parties with them and people grill chicken, hot dogs, hamburgers, etc. He won't eat any of that.
There are only about a dozen food he eats. I think they indulged him when he was little and kept waiting for him to grow out of it.
Anyway, when they went to Disney last year they revolved most of their meals around him. The stayed at the Beach Club and got pizza from the window at Spoodles most nights and then went into Epcot. The bottom line is that it's their family and if they want to revolve meals around their one picky child, that's their business. I can tell you that their 9 year old daughter and 3 year old son eat normal food. In fact, their 9 year old gets really sick of pizza. When we ordered it one night at our house, she sighed and asked me if she could have cereal.
I think disney has dealt with picky eaters before. Plain pasta is probably something most TS restaurants would prepare for you. I would just ask.
