Almost every table service has a kid friendly none adventurous eater option. Here are some examples:
Chefs de France has Chicken Strips served with Pasta
La Hacienda - Grilled Chicken, Tacos, and Cheese Quesadillas
Restaurant Marrakesh - Chicken Tenders, Hamburger
Via Napoli - Margarita Pizza and Spaghetti with Meatball.
I would suggest taking a look at what you might like then check the menu's posted on the WDW website to see if your child would be interested in any of the kid's entrees.
