I know you can get Paninis at the New York Sandwich place, but thats in Disney Village... hildasmuriel posted some piccies up from when she went there on her last trip and it looked rather yummy! There's always the option of having a Croque from Victoria's Home Style on Mainstreet- It's basically like a toasted sandwich, but they look amazingly yummy! There's some pics on the Victoria's thread in the reviews section....
Are you looking for Counter Service places that will alternatives to burger and fries? If so, theres a few options:
*Fuente Del Oro- Frontierland: Sells Tex Mex style food
*Cowboy Cookout- Frontierland: A bit more basic, but serves yummy looking potato wedges, etc.
*Colonal Hathi's Pizza Outpost- Adventureland: Serves Pizzas, Garlic Breads and Salads.
*Pizzeria Belle Notte- Fantasyland: Pizzas, salads, etc.
There's probably some more I've forgotten, but check out the reviews threads as some of them have pics of the food from these places on!
